Updating FriendSelectorFragment

Setting up sending creep data to a new creep on exit from FriendSelector.
Also setting button to return you to home page at the same time.
CountDownTimer not yet working...need to modify in CreepListAdapter.
Added ability to add and delete creeps from lists.

Can now delete creeps from either list, and add creeps to your creep list.
Creeps are added to or deleted from main arraylists (via CreepLab) in each
case.
