Found & fixed two memory leaks:

Browse Source 
- computeActions would leak a ManaCost.  This was fairly minor.
- AIPlayer::SelectAbility had a major leak.  Basically, there's some code that pulls a random number for an efficiency check - if the action's efficiency value was below that random number, the action pointer was cleared, and none of the actions that were to be discarded would be deleted out of the rankings map.  I've switched out the rankings container to not contain action pointers, but real action objects, so regardless what kind of logic is implemented, the map will properly clear out its objects upon destruction.
