Removed client/toolscreen.lua: It is no longer used in Gmod13
This code appears to be exactly what is now present in Garrys cl_viewscreen.lua
Which we switched to using in the Gmod13 transition.
Cam Controller: Fixed FOV changing on initial spawn
Also fixed changes to input Zoom working when cam is off
Fixes concerns in comments of c1fe96578be6e8e3caf1e2583cc47f67a3674ffb
