[Scott Ritchie <s.ritchie73@xxxxxxxxx>]

I've attached my new working AdminViewBuilder.

Make sure you restart your browser or sign out of mugle before testing to
prevent unexpected behaviour between the changes.
Now that i've made that work i can use that to make the Badge etc work with
similar functionality.
Also Should we make a window pop up to confirm the removal of a
devteam/badge/game?

I'll commit it when i get home tonight and can get on over port 22.
