Qt: Add next / previous sequence shortcuts.

Add next (N) and previous (P) keyboard shortcuts. The GTK+ UI uses the
down and up keys, but we're already using those for panning the Y axis.
Add a scroll margin when using N and P.

Add mouse wheel and trackpad support.

Disable mouse dragging for now until we figure out how to limit it to
our axis boundaries.
