Yaga Unaward Badge 0.4

Adds the option for users that can give out badges to take them away.

This can be useful for spammers or erroneously awarded badges.
Users with the Yaga.Badges.Add permission get the ability to remove badges and their points from users.

Note that for automatically awarded badges, if the rule criteria for receiving this badge are still met, they will immediately receive the badge again, once they browse the forum.

This means you have to make sure to remove the condition first. For example, if a spammer receives the 100 postings badge, first delete the postings, then remove the badge.
