modules/rkt: track last scene in ctxt->last_scene

Prepartory commit for pausing playback upon entering 99999 scene

It needs to trigger only on the edge of entering the scene to
permit RocketEditor to unpause playback even if still in scene
99999, if that's what the user is trying to do.  It'd be annoying
to have it just keep asserting a paused state until the scene idx
leaves 99999...

But this also enables triggering anything on scene change edges,
for future stuff.
