[CLEAN] or: reverted website-al unnecessary change
[CLEAN] setup.py: reverted website-al unnecessary change
[CLEAN] [DOC] renamed misc_qweb.rst file into ir_qweb.rst
[CLEAN] res_config, res_users: cleaned call to imd.get_object() + code cleaning
- res_config: raise by default, no need to set the argument at True
- res_users: directly embedded get_user_groups_view code inside update_user_groups_view.
The try / except is still necessary, because when installing a new db, groups and users
are created before the user_groups_view view effectively exist. Due to some circular
references, the try / except is therefore necessary to install a new db.
[CLEAN] [REM] ir_qweb: removed access rules on the various ir_web models
as those are abstract models. They should not have any access rules.
[CLEAN] ir_qweb: simplified and cleaned QWebcontext implementation
- now using openerp.tools.safe_eval, instead of a custom eval with custom builtins
- removed undefined_handler, hardcoded to a lambda function that returns None for
a missing attribute

tools.safe_eval: added a parameter locals_builtins. This allows to copy the builtins
in the locals. This hack is due to the fact that the locals always returns None, allowing
to simplify templates. Otherwise we would have to test the existence of each variable
before actually using it.
However as the locals always return None for every key, the globals are never checked.
Copying the builtins inside the local allows to have a complete locals, but sligtly
break the globals/locals separation.

To be reviewed and approved.
[CLEAN] ir_qweb: removed commented and now dead BUILTINS
[MERGE] [CLEAN] Part I of cleaning and improvements of the server branch of website-al, after review with our Masters. All Glory to Our Masters.
