GuitarPro tablature import issues

The latest version of GuitarPro saves as XML. For tablature, each note has a STRING, FRET and MIDI note. The MuseScore importer (importgtp_gp6.cpp - line 1220) reads in this info and then creates a Ms::Note by first looking at the MIDI and if that's not there it uses the STRING. In other words, it ignores the tablature and computes the STRING/FRET from the MIDI every time.

Also it is not dealing with chords correctly and ignoring the "Words" and "Music" credits -- see image below. The top image is GP and the bottom is MuseScore.
