[FIX] survey: in prepare_result, result_summary variable could be returned without being initialized (error in question.type maybe, but anyway should be more secure)
[FIX] website_forum: fixed (un)publish management on the profile. Partners are now also published by default. Better protection of displayed profile: only publis profiles with karma >= 1 are displayed on the forum, to avoid allowing external users to browse the user lists. Some cleaning / improvements in the bio edit form that was a bit buggy.
[FIX] [IMP] mail: fixed mail sent to users being redirected to their partner profile
leading to potential issues.

Now the behavior is back to its previous version, posting on the user creates a private
discussion. Fixed management of model variable in message_post to avoid posting messages
on the mail.thread model.

Classic inbox writes on partner, with hr it writes on the employee profile, like previously.
