Pretty much completely rewritten theme with custom HTML translator and a
few parts of the old theme extracted to their own extensions.
Banner images thought not to be that huge after all, and not worth the
hassle of them living in a different repository.

The `set` method of the one2many class returns a list
of the fields that require recomputation,
the computing of the function fields being delayed
for performances reasons.
Nevertheless, if the `set` method was called
through another `set` method, in other words,
nested `set` calls, the fields to recompute returned
by the second, nested, call to set were never recomputed,
the result list were simply lost.
e.g.:
```
create/write
│set
└─── create/write with recs.env.recompute set to False
│set
└─── create
with recs.env.recompute set to False
```
To overcome this problem, the list of old api style
compute fields to recompute is stored
within the environment, and this list is cleared
each time the store_set_value has done its job of
recomputing all old api style compute fields.

The computation of property `digits` was creating a new cursor to call the
function that determines digits. This technique is fragile because the current
cursor may have pending updates that the new cursor will not see.
The issue was discovered by Cécile Tonglet (cto). She observed an infinite
loop during a database migration, and a traceback inside the loop showed the
presence of the `digits` property. This change fixes the infinite loop issue.
In a workflow context (for instance, in the invoice workflow),
context is not passed.
Therefore, relying on the 'recompute' key being the context
in order to not recompute the fields does not work with Workflows.
It leads to huge performance issues,
as fields are recomputed recursively (instead of sequentially)
when several records are implied.
For instance, when reconciling several invoices with one payment
(100 invoices with 1 payment for instance),
records of each invoice are recomputed uselessly in each workflow call
(for each "confirm_paid" method done for each invoice).
With a significant number of invoices (100, for instance),
it even leads to a "Maximum recursion depth reached" errror.

This reverts commit 8cd2cc8910.
It turned out that forcing recomputing fields as user admin breaks some
existing behavior. Instead, we make the recomputation as user admin explicit
by adding compute_sudo=True in the field's definition.
Unify and refactor exception handling in framework and addons.
The generic `except_osv` is now deprecated, and replaced by more specialized exception subtypes:
- `UserError` (renamed from Warning, as it conflicts with the built-in `Warning`) raised when a non-technical error occurs during a business operation. It could be a missing information in the data provided by the user, or a misconfiguration.
- `AccessError`: raised when any operation is denied because the user conducting it does not have the required access rights.
- `AccessDenied`: raised when an operation that requires authenticated access is attempted via an unauthenticated request.
- `MissingError`: raised when an operation is attempted on a record that does not exist.
- `ValidationError`: raised when an operation violates a SQL or Python constraint.
- All other exceptions are internal errors due to a system problem or bug, and raised untouched to the client-side, which should display a traceback.
All exceptions take a single message argument.
The `test_exceptions` module has been updated to showcase both new and old (deprecated) exceptions.
A great many old `except_osv` had a useless title with "Error!" or "Warning", those have been removed, as this is handled by the client-side widget that displays the messages.
This commit introduces a more consistent policy for logging errors and warnings:
- All messages that do not require administrator attention should be logged at INFO level or lower. This includes all errors that are notified to the user in a friendly manner, even for access right problems or validation errors during business operations.
- All messages that indicate a likely misconfiguration or malicious use by the users should be logged at WARNING level, as they typically require administrator attention.
- All other unhandled internal errors cannot typically be handled by the user and should be logged at ERROR or higher level, as they require immediate administrator attention.
This fixes an issue where the same function is used in several model classes:
once the function is wrapped for the first class, it is erroneously considered
as a wrapper for the second class, and is therefore not wrapped in other
classes.
When an onchange returns a change in a 2many field line (a '1' tuple, update), avoid to return all fields of the *2many field but only the altered field.
Otherwise, the web client regard all the fields of the 2many as dirty, and try to write on all fields (even if the value is the same, thus)

The method _prefetch_field() was accidentally prefetching fields to recompute;
which was skipping the actual recomputation, since a value was put in cache.
But sometimes the field's value was fixed by an extra recomputation of the
field. Here we remove the extra recomputation and fix the cache corruption.
This fixes a bug which is usually triggered in module account_followup, but
does not occur deterministically. Some recomputations of computed fields are
apparently missing. Environment objects containing recomputations todos and
kept alive by a WeakSet, are removed by the Python garbage collector before
recomputation takes place. We fix the bug by moving the recomputation todos in
a non-weakref'ed object.
Fixes#966
* As a preallocation optimization, ``list()`` calls ``__len__`` on its
parameter if it's available
* Before Python 2.7.4, WeakSet has a bug[0] where ``len()`` is unsafe: it is
done by iteration and weakrefs may be removed from the underlying set during
the iteration
As a result, the safety feature of listifying a WeakSet to ensure we have
strong refs on all items during iteration may blow up.
Wrapping the weakset in a ``iter()`` makes ``__len__()`` invisible and ensures
we're within the IterationGuard[1].
Which now that I think about it means we *should* be able to safely iterate
weaksets in the first place and may not have needed to listify them...

A squashed merge is required as the conversion of the apiculture branch from
bzr to git was not correctly done. The git history contains irrelevant blobs
and commits. This branch brings a lot of changes and fixes, too many to list
exhaustively.
- New orm api, objects are now used instead of ids
- Environements to encapsulates cr uid context while maintaining backward compatibility
- Field compute attribute is a new object oriented way to define function fields
- Shared browse record cache
- New onchange protocol
- Optional copy flag on fields
- Documentation update
- Dead code cleanup
- Lots of fixes
