Moved all animation ordering logic to callers

Previously, CBattleAnimation & inheritors were controlling animation
ordering - e.g. which animations should play after which.
Now, this is controlled by caller, e.g. BattleInterface & its
controllers.
H3 animations are fairly linear and can be split in stages which are
already somewhat implemented via waitForAnims
