Implemented GPL commands JustTalk and JustStay.

The basic commands are done.  It remains to implement handling music (after
we play it at all), fading palette, and controlling the quick-hero and
speed-text flags (after I find out what they do).

Now the dragon switches between talking and staying during dialogs.  However,
the left/right direction doesn't work yet, because we don't respect _lookDir
and _useDir yet.
