Merged 0.6 branch into trunk.

Permissions management was rewritten. Some permissions can now be specifically defined for non member and anonymous users.
This migration:
* is irreversible (please, don't forget to *backup* your database before upgrading)
* resets role's permissions (go to "Admin -> Roles & Permissions" to set them after upgrading)
