Add a very basic, naive auto-move command
Add a very basic, naive auto-move command, which just steps the player
in a direction until they collide with something, regardless of any
surrounding beasties who might want to eat them.

There's a lot of other stuff going on here - in order to get this
working the way I wanted with a slight (I settled on 50ms) delay between
every step in these autocommands while still redrawing in between I had
to do all the extra machinery for custom Brick events with a channel,
and then at the same time adding the bits for actually executing
autocommands in a general fashion (because there will definitely be
more!) hit my threshold for size for App.hs which sent me on a big
journey to break it up into smaller files -- which seems actually like
it was quite successful. Hopefully this will help with compile times
too, though App.hs is still pretty slow (maybe more to do here).
