Add another UCP tab for non-default badges

[ghost]

Like the 'Default badges' tab but will list "special" badges the user earned. This is consistent with the current system which allows the user to select badges from default/special badges tab and then manage their order in the profile badges tab. Parts of the 'default_badges' code can be reused for this.

Maybe combine this with the default badges page, listing them as options in the same (visual) table?

I have proposed an implementation for this in #19.

Implemented as suggested. Renamed Default badges to Select badges and Profile badges to Order badges.
