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'`
Move code from website_forum allowing to edit its own profile. Otherwise
fields to update are not white listed. Also add an unpublished flag when
seeing unpublished users in order to know it if you have access to
depending on ACLs.

Email validation was necessary on the forum to be able to begin to use the forum
(ask or answer questions, vote, etc..)
As the new elearning also uses karma since 705376a982,
the email validation is now also necessary in the eLearning platform.
This is why this commit is moving the email validation process to website_profile
and extend website_slides (eLearning) and website_forum to use this feature.
In function of where the user asked to send him the validation email,
the user is redirected on the forum or on the elearning when he clicks on
'Validate my account' in the received 'email validation' email.
