[MERGED PR] Gives captain a mindshield

[Cleaverwolf]

I think Mindhacks would be a lot more interesting mechanically if they kind of worked like rev implants. Instead of Mindhacks allowing you to instantly take someone over with one click, you would have to damage your target significantly (near crit or crit) at which point the mindhack will kick into action and will heal the target out of crit (bullet fragments be damned). Alternatively, you would be able to flash/stun your target and the mindhack would also work. Just a thought.

With this implementation I don't think mindshields would be necessary.
