Improved V/TBOGT Schafter

I grew tired of looking at IV's ugly original Schafter, so I decided to replace it with the newer version first seen in TBOGT, then later in V. Since it was replacing the original IV Schafter, it needed a stock and gang variant, so the widebody version from TBoGT was out. TBoGT's version is basically identical to V's, so I used TBoGT's Schafter3 to make the convert go quicker. I used tuning parts from V to make the gang variant.
