Slayer Bossbars innit

Should cover #908

I don't think the render mixin is necessary. I would add it to BossBarHud#bossBars and remove it when you set the bar to null. The current implementation also stops any other bars from rendering.

I mixin'd on render to be able to explictly cancel other bars from rendering. I originally had it to just appened a bar but people disliked multiple bars in the video i demo'd it in, thus i mixin'd to render to cancel any 'quest' bars for the duration of the fight

Ok, I'll just make some naming and formatting fixes then.
