The percentage computation of statistics only uses the consumed ratings
>= 1 (through `rating_get_repartition`), while the initial search of the
first 100 ratings doesn't have this restriction. It leads to an
inconsistency between the ratings displayed and the percentages
computed.
Moreover, if there are less than 100 ratings, the percentage might not
be a natural number => use of float and round.

Since saas-3, website controllers use `request.website.render`
to render the template of a web page. This was kept for retro
compatibility. It's time to stop using deprecated stuff.
Same for `_render` method on website.
'json' route don't use `request.render` since
`JsonRequest` has no `render` method.
Migrate the models and controller to new API. Renaming xml id according to convention, renaming openerp tag into odoo tag. Add comment strings and documentations.
