Approved Users

[jfredett]

There should be a list of "Approved Users" for whom certain commands are allowed. There should therefore be a UserCapability class which supports a approved_user? class method, so that when I pass a nickname into the #approved_user? method, it returns true if the user is approved, false otherwise.

The ChannelChanger plugin has a UserRole class that implements this. It should probably be refactored though.
