GTA 5: Sentry Function

//-----------------  Sentry Gun  -----------------
//
//Includes a Variable TargetName[] that can be used to either display targeted players name or just "Vehicle"
//Configurable timeout on variable Called:Timeout
//Configurable weapon on variable Called:WeaponID  (http://www.se7ensins.com/forums/threads/weapon-and-explosion-hashes-list.1045035/)

//You can switch Players as target with bool:PlayerTarget
//you can switch Vehicles as targets with bool:VehicleTarget
//Vehicles always get priority over players
