Favorites (?) not linking to profile page

[jaredatch]

When logged in and viewing a topic you will see "Add this topic to your favorites (?)" at the top.

Currently the (?) just links to the topic.

Like past versions, this should probably be linked to the favorite section of the user's profile, eg:

​http://wptrunk/forums/users/admin/#bbp-author-favorites

Patch that restores the (?) to bbp 1.x functionality - links to the favorites section of the user's profile.

Thoughts? :)

(In [3813]) Use proper permalink in bbp_get_user_favorites_link(). Props jaredatch. Fixes #1790.
