Changed NPC headshot damage scale to 2

Because 10 is way too much
Changed height of PropSelect on most tools to 4

Because height of 6 for 2 models is kinda weird. Thrusters had height of
2, which is too small for that much models.
Added model selection for Lamp tool

It was in todos of the tool, also there is one unused model of
projector.
Improved faceposer

Added reset button and added select yourself on reload. Not sure about
last one though.
