Currently line was incorrect as the purpose is to ensure all lines of
the scheduler are sent. Currently not send lines are filetered and therefore
not taken into account. This commits fixes it.
The previous line was O(n^2). With n=1200 like we just have now,
things didn't look good for this loop and confirming an attendee
registration to such event took approx. 13 seconds.
Since the list comprehension is in no mean linked to the value
of "item" in the filter, I simply moved it out so it is only
computed once.
- dates are editable even in confirm state. Only events in done states are
not editable.
- the print badge button is actually a button to edit badges, so let us udpate
the name
Simplify contact / addresses management. Contact now use the same
address as their parent. Invoice, delivery and other contacts
have their own address. Default contact is removed; the default
is now contact.
As contact automatically use the company address, and other types
use their own, use_parent_address field is removed, leading to
some simplification in the address management.
Also add company_type field, to have a selection field instead of a
boolean one when display company / person choice. This is an interface
field build on the is_company field, to create the minimum change
and avoid disturbing the logic based on is_company. When migrating
to the new API, its implementation will be cleaned.
