Subject: [PATCH] Add Vehicle Inputs To Cam Controllers And EGP Huds (#3263)

* Add Vehicle Inputs To Cam Controllers And EGP Huds

Adds a "Vehicle" input to Cam Controllers and EGP Huds, inline with Pod Controllers.

I understand this is somewhat redundant for Cam Controllers but I feel it's relevant.

I am working on some addon stuff where a seat may not exist on spawn (generated by another entity). In this case, wire I/O is a reliable way to persist linkages through dupes.

* Add 'Vehichles' Input To Pod Controller And EGP

Instead of adding 'Vehichle' to Cam Controllers and EGP

* Update gmod_wire_pod.lua

* Fix

Redundant check removed.
