Feature request: add support for prop_vehicle_driveable

[Tiagoquix]

When a player is driving a prop_vehicle_driveable in TF2 (thanks to this plugin), several fake angle detections easily occur due to the way the vehicles' camera works.

I would like to request that if a player is in a prop_vehicle_driveable (normally only granted by a server admin when spawning a vehicle), StAC purposely ignores any possible fake angle detections from the player.

It's OK to be a ConVar with this ignore behavior turned off by default if you prefer.

I understand if you don't want to do what I'm requesting, as this is outside the scope of this plugin, but here's my request anyway.

Thanks in advance.
