Subject: [PATCH] Fix Room Bundle currency updating. Before: The currency was
 taken when purchasing a room bundle, however it did not send a composer
 window to update the client, also it still took the currency even if a user
 had maxiumum rooms, meaning that the user was charged even if they didn't get
 the room!
