PVP fixes

1. PvP not moving lag (yes, this is being worked on)
2. Stealth: a few options to make spies killable when versing 5-6 players in an open field: pick or choose, many people might have better ideas, but here’s my go at it:
a. Stealth tool gives drug flash after 3-5 times of use. More usage makes drug flash get worse and worse. (from Bug)
b. Stealth tool does not give 100 percent stealth coverage (i.e. 5 sec cool down after every use)
