When dragging multiple tracks from from the left pane onto a track in the right pane, Picard should connect the first track from the left to the dragged-onto track on the right, and then each subsequent track should be connected to the subsequent tracks on the right.

Currently Picard dumps all dragged tracks onto the single track of the release, which makes little sense that I can see.

This helps when adding groups of tracks one-by-one to a large release.
