added splash grid for AOE abilities
added splash damage to Quake
modified behavior of ProcessHit to recognize negative damage as a healing spell and act accordingly. also made heal heal, instead of hurt
added support for abilities that can target any square
pulled out the _targettingCenter property from the BattleBoardLayer and instead forced the caller to generate a grid that is oriented to 0,0 just like the battle grid
added a delay state that can be used to delay state switching. right now, it is just used to add a 1 second delay at the end of all hits
Fixed a slight graphics bug where a hit indicator would appear to jump on the first frame
added a 50ms delay between selecting an ability and returning to the player state. this fixed a bug where if you queue Heal on an ally, you'll also select that ally. this delay puts enough gap between the two that the same mouse click to choose Heal on that ally will not select that ally.
misc cleanup
