Closes #1260

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

- move packaging stuff to setup
- remove historical stuff
- remove oe, odoo-cmd-fme will be merged with the convered commands
- add an odoo.py script to run odo and boostrap it
- simplify README
- prepare to move documentation to the github wiki

in all searchview, the 'Group By...' looks weird, next to the Custom
Reports and Filters.  This change was requested by the upper management
