Nerfing defib and repair gun

Defib charges really fast and has infinite uses, which makes it almost impossible to defend against when they can be respawned over and over again. I personally think defib should have a limited amount of uses before breaking or just stop working.

The repair gun has no cooldown and can just repair a transport or tank infinitely. The repair gun should have a cooldown so that if it's being used to spam repair a vehicle, there's a time period during which it can be destroyed.
