Made DarkRP compatible with Passenger mod
Added vehicles by table option

Note: getting passenger mod to work with TDM is a bitch (at least it was to me) the TDM bus kept overriding the passenger mod, causing the bus to have 0 seats.
This is not the fault of DarkRP.

TDM Bus example:
AddCustomVehicle{
	name = "bustdm",
      	model = "models/tdmcars/bus.mdl",
      	price = 10
}
Made formatting in github nicer
Fixed Lua error with cached queries and MySQL.
Fixed queryValue printing the previous error when using SQLite.
