Multi is the default api for methods, it is not necessary to explicitly
decorate methods with it, adds clutter and most people use it because
they see that the rest of the code uses it.
Done with `find . -type f -name '*.py' | xargs sed -i '/@api.multi/d'`
Before this commit, it was impossible to know which view was the one searched
if there was COW views.
Indeed, since multiwebsite, views might get duplicated from one website to
another. Then, when searching for an ir.ui.view in a form view, every
duplicated view would be listed next to each other with the exact same name
without a way to identify which one comes from which website.
This commit will suffix the view name by its website_id if there is one.
To do so, we use the context key that has been introduced with 62d73253f3.
