* made modelView take a QWidget-pointer argument * trackContentObject-ctor now calls track::addTCO() directly * optimize various loops to use iterators/const_iterators instead of a running index variable * drag'n'drop doesn't fool around with pointers anymore - instead use unique journalling-IDs * moved drag'n'drop handling code from knob to automatableModelView so that all controls can benefit from that git-svn-id: https://lmms.svn.sf.net/svnroot/lmms/trunk/lmms@1164 0778d3d1-df1d-0410-868b-ea421aaaa00d
