Before this commit, the 'magic' model calendar.contacts name was misleading. This model is only used to save calendar view preferences in the calendar app.
As the calendar events are already mentionning attendees, partners, users, the 'contact' name for a technical field was confusing.

TL;DR A bit of magic and ... Pouf ... all virtual events are now real records.
Purpose
=======
The current implementation of recurring events uses "virtual events" to represents all
events in the recurrence. Only one event is stored in the database. All other events are
dynamically built and sent to the web client which sees them as real records.
This implementation is old, difficult to read (6 years of changes and bug fixes) and
has become more and more difficult to maintain.
A fresh start would be welcome.
Specification
=============
When creating a recurring event, a `calendar.recurrence.rule` record should be created.
This model holds the rrule configuration and is responsible to manage events that result
from the rrule.
When a new recurrence is created, all resulting events are also created (stored in the
database). No more virtual events.
To avoid an explosion of events, a maximum of 720 events is created. With 720 events,
a daily recurrence lasts for 2 years and a weekly recurrence lasts for 15 years.
This strategy is used by Google Calendar and seems acceptable in most cases.
A cron job could eventually be introduced to generated more events as the end comes.
This allows to introduce an new rrule end type: 'Forever'. This is actually a shortcut
to create a recurrence running for 720 events.
Inspired by Google Calendar, new possibilities are introduced when modifying a recurring
event (e.g. change the name, add an attendee):
- Modify only this particular event (the event is still part of the recurrence)
- Modify this and following events (events are still in the same recurrence)
- Modify all events
In a similar way, when updating the rrule of an event (e.g. from every Monday to every
Tuesday), the user can choose to:
- Modify this and following events: the recurrence is split. The first part remains
unchanged but now ends when the second recurrence begins. The second parts is the
updated rrule.
- Modify only this particular event.
- Modify all events: Forbidden (same as Google Calendar)
Note: when events are "moved" because the rrule changed, the events are not actually
moved. They are unlinked and new events are created (See "Some design choices explained"
section).
Some design choices explained
=============================
Where to store the rrule?
-------------------------
Two options were considered.
1) Store the rrule on an event, each event of the recurrence having a Many2one
to the parent_id, aka the Master Event of the recurrence.
2) Store the rrule on another model: `calendar.recurrence.rule`. Each event in the
recurrence having a Many2one to the recurrence record.
Both options have pros & cons. But there is no clear winner.
However the actual business logic of handling the recurrence creation/update
would be the same.
Where the rrule configuration is stored is the only main difference between both options.
And this is probably the easiest part of implementing recurring events.
With that in mind, option 2) is chosen. It allows to clearly separate recurrence
logic from the events themselves. It is also the "correct" way of modeling data to avoid
many empty columns for most records.
Reusing events on rrule update
------------------------------
When an rrule is modified, events should also be updated.
In most cases, current events are unlinked and new events are created from scratch.
Only events exactly at the same time before and after the rrule update are kept.
Trying to reuse other events would require an obscure and arbitrary heuristic.
(Imagine an rrule every Monday that is changed to every Tuesday and every Friday.
What would you do?).
This implies that any change to a specific event (name change, attendee added, chatter
messages) is lost. This tradeoff seems acceptable as updating an rrule should not be
that frequent. Moreover, Google Calendar also works that way so why not Odoo?
Reusing events on events shifts
-------------------------------
On the calendar view, drag and drop an event to shift the entire recurrence.
One way to handle the recurrence shift is to apply the same timedelta to all events.
Now events are correctly positioned... except for events that were specifically
moved. Those outliers needs special handling.
This also introduces some behavior inconsistencies:
when an rrule is directly modified, events are not reused, but when the rrule is
modified by drag & dropping an event, events are reused. This option needs more code to
handle the shift and the behaviors are not consistent.
The chosen option is to find the rrule configuration from the dragged event (this is
easy) and update the recurrence with those new rrule values. This brings us back to
an rrule update (see above): code reusability yeah; one behavior to rule them all yeah.
One downside is that outliers are lost (but Google Calendar also works that way).

Purpose:
Having the res_group defined in base and sales_team auto installed
with mail doens't make sense.
- Move the empty res_config class and the related view from
base_setup to sales_team (base_setup only contains the 'General Settings'
model and views
- Move the 'sale' related content from product to sale module (Access rights,
menuitems,...)
- Set sales_team at autoinstall False. The module is installed when needed by
crm or sale for example
- Set sales_team as a dependency of voip. (Access rights defined for configuration
purpose)
- Set sales_team ad a dependency of subscription (Access rights issue too)
[FIX] account: move some ir.model.access to sale module
[FIX] payment: Move some ir.rule to website_sale
[FIX] stock: move some ir.model.access rule to sale_stock
[FIX] project: Move some ir.model.access rules to crm_project_issue
[FIX] mrp: Move some ir.model.access rules to sale_mrp
[FIX] calendar: move some ir.model.access rules to crm
Rename xmlids accordingly. Example: 'base.group_sale_manager' becomes
sales_team.group_sale_manager.
[ADD] sales_team: See own documents => See only his sales team
Moved the "User: Own Leads Only", "User: All Leads" and "Manager" groups from sale and crm
into sales_team module. Add the record rules so that user can see only his Own Sales Team
if "See Own Leads" is sales right and can see all sales teams if he is having sales rights
of "See All Leads" or manager.
This branch need more testing instead of doing 10 fixes. A lot of issues are occuring
when installing modules in different orders.
This reverts commit fa6e415cdb.

- Access Right too restrictif for user
- Bug UI between Firefox and Chrome
- Bug UI many2many_tag cursor on bullet
- Temp Fix on email_template to manage partner_to
- Manage attendee from hr_holidays
- Manage avatar_model in sidebar_items for filter (res.partner was hard coded)
- Remove quick add from HR-holiday, because some field (as day) is calculated on event "onchange"
