Swap out active mode

[Phenidate]

So there's very little reason to make players micromanage the active/passive mode with the auto attack system now. (if anything its holding it back making it clunky. Getting it to auto attack between targets feels awkward right now)

What we need to do is swap it out for a 'start attack' button. Hitting this button or using a combat action should put you into active mode until combat is over or you run away.
