Subject: [PATCH] TrackContainerView: added support for dropping ResourceItems

Added support for dropping ResourceItems on a TrackContainerView. Now
it's possible to drag samples, presets and soundfonts from the new
ResourceBrowser into Song Editor or BB Editor (code needs to be ported
to new Song Editor later).
