fix for using the CMenu in nonvehicle entities (#1581) * fix for using the CMenu in nonvehicle entities improved version of my fix. earlier description: if you open the context menu while in a prop_vehicle_crane you will get a lua error like this [ERROR] lua/includes/modules/properties.lua:114: attempt to call method 'GetThirdPersonMode' (a nil value) 1. GetHovered - lua/includes/modules/properties.lua:114 2. fn - lua/includes/modules/properties.lua:174 3. Run - addons/ulib_557962238/lua/ulib/shared/hook.lua:109 4. fn - lua/includes/modules/halo.lua:149 5. unknown - addons/ulib_557962238/lua/ulib/shared/hook.lua:109 this is because LocalPlayer():GetVehicle() return the crane you are in, so the IsValid check will return true, but since it's not an actual vehicle, calling a Vehicle function will cause a lua error.
