crouching

Hello, we have crouching in the game but it lacks any use in current game (1.0.4), please let players to use weapons while crouching. Also I'd like to see crouching in shieldwall formations by AI.

This a bit connected to my previous post about Sprinting, but another aspect of first person games that I kind of miss is pressing Ctrl in order to crouch and sliding if pressing Ctrl while sprinting. Crouching could be useful in order to increase ranged accuracy or reducing "detection" in case...
