Changed BuffRezables behavior
(#323)
* Adjusted BuffRezables to not use any group buff if any group member corpses are in range
Current behavior is one PC will be rezzed, and while the rez is on cooldown, we will often buff them. The rez will come back up, but we are still busy buffing rezzed dude, and we don't rez dead dude. Then we rez dead dude, and do the entire thing again, because now HE needs buffs too. Etc.
* Minor bugfixes and additions
