Power Stare is more trouble than it's worth

[CplPibald]

Power Stare makes melee combat extremely difficult. Attempting to attack a mob simply pushes it out of reach of your weapons, often before you can even swing a sword. With something like a zombie this is an annoyance because they'll just keep coming back. For a ranged attacker like a skeleton or blaze it's actively detrimental because you're still in their range but they've been pushed out of yours.

Power Stare needs a way to be turned on and off during combat depending on the situation.

I wrote a fix for this that makes a check for player.isSneaking() before applying knockback. That way you only power stare when crouching down. It seems to work pretty well.
