[REM] rating_project: kill the module and move feature in project

Impacted modules: project, rating_project,
sale_service_rating and website_rating_project.

Removed modules: rating_project and sale_service_rating.

Move code to empty 'rating_project' module, in order
to kill it.
Code is not modified, simply copy/paste at the right
place in 'project' module code.

However, 'enable rating on task' options is convert
into a res.groups that can be activated from the
project settings.
