Pending Abilities are always Added then Removed (thus ordering is not preserved)

We should probably keep a Queue of the Gameplay Abilities Add/Removed rather than two separate lists.  That way we can get the ordering right.  I suspect there are lots of ordering issues if we look carefully.

Create an Ability that performs a function, then grants itself back to you upon removal.  Notice that there is an issue because all of the Adds are performed first, then the Removes.  The result I believe is that you will not get that GA added again, it will instead be added when some other GA gets applied.
