Backstab & Back hit damage implemented (But not updated yet) (Patreon)

As mentioned before, the ghost will be boosted by a special backstab one-hit kill ability, this is working properly now. Backstab will one-hit-kill a player and half the suspicious mark time. 

Added a 50% extra damage for shooting the backside of the player. This value might be further adjusted in the future. 

Added a height detect function to snap all health bars right above players' heads no matter the height of the avatar. 

Network structure overhaul to stabilize gameplay procedure. Now it should be much more reliable than in the close beta version.

Renamed "Corruption" into "Suspicious" stage for easier reading.

The quest build is updated to the weekend beta version, but I'm going to hold the update until I got the other main issues solved.
