minor
a few changes in camera controller (now it always look at the player head, also added zoom-in/zoom-out animations at the gesture start/end)
also added new console command -inc_gestures_give arguments: (steamid/nickname, gesture-name)
Idk why this might be useful, usually you would like to use INC_GESTURES:GiveGesture(play, gestureName) for compatibility with other addons. But the customer asked, so I added this :D
