- Moved "extraPayment" cancel verification into ActionLayer (was in GuiLayers)
- added "HUDDisplay" MTGAbility (displays damage/graveyard info)
- Added option to NOT interrupt own's spells and abilities. Allows smoother gameplay. We should add a "quick options" menu ingame to change those options on the fly
* Add the rolling phasebar.
* This is a preview version. It shares most of the code with the definitive
version, but when the real code is checked in, this will be deleted.
