PCs/monsters can now get temporary stat modifiers that last for a specified number of turns.
Temp stat mods now wear off at end of battle if they haven't already
BatCmds can now have an onStartRound function, which is applied to the user at the start of the round -- in this way, the command you pick can have an effect (for example, on your defense, or on your initiative order) before your turn comes up.
PCs now have individualized in-battle and out-of-battle spell lists, which are used to construct the in-battle spell menu and out-of-battle spell menu.
