Updated wire light to new GMod light
Merge branch 'light1' of https://github.com/Jack37/wire
"Updated wire light to new GMod light" @Jack37
Closes #368
Light: Switched to MakeWireEnt
Renamed ShowOutput to SetRGB, since the former generally means "build overlay"
Moved SetRGB's delta check to TriggerInput, so Setup's call is always applied
Light Stool: Wake physics when spawning ropes
Clarified that CPanel's 'Color' is 'Initial Color'
VThruster: Fixed initial overlay always showing 2000
Graphics Tablet: Removed extraneous include('shared.lua')
