[Feature][Total Hack] Keep facing the same direction in space

[kyle2143]

This is so tiny, but I just had this sitting around so here it is. Due to the nature of how moving from tiles works, I just had to create a temporary variable to store your original direction when moving in space due to inertia.

I had some other things I wanted to do in this vein, making being in space tiles slightly more interesting visually like having a floating animation like TG does, or orienting your sprite to have your feet facing a wall if you're wearing magboots. But those aren't really predicated on this so there's no reason to include them here.
