Some Minor changes for Mccree

Combat roll: Immunity on use, so it actually feels like you are dodging attacks.

Flashbang: Projectile speed increased, reason being he’s throwing it with his robotic arm, shouldn’t he have the ability to throw it faster then normel? just an idea.

Something bothers me about mccree’s flashbang, why does he carry 3 but only use 1 every 8sec, don’t get me wrong it’s a very stronge ability but it just bothers me.
