Mack Ultraliner convert from ETS2

– Tuning (Same as ETS2 Version, can add new tuning but red errors in log)
– Correct Sound (not ETS2 Truck sound)
– Corrected data (price, names, etc..)
– Added missing files (.dds/.mat/.tobj)

Tested ATS v1.3.1.1

There are still some small mistakes but nothing major (red/yellow errors in log, sound is not perfect, etc..). Surely fixed in a next Update.
