instruments can load their patch'es drummaps

automatic setting of drummap according to patch
this is turned off when the user manually changes the drummap
TODO: let him turn it on again
moved MidiTrack::read/writeOurDrummap out to helper.cpp
extended xg.idf and gs.idf to ship the drummaps

still work in progress, but should be usable and stable, though incomplete
