Triggers need to know and save more stuff

[frazazel]

Right now triggers only know what Combatant they're attached to, and what Action to call (as well as what Effect/Combat/etc. they belong to, so they can be properly deleted).

Triggers will also need to know who triggered them (in the case of a counter-attack skill, for example). Triggers should store who created them in the first place (so that if they drain the health of the target or something, the correct Combatant will gain health).
