Speeds up space movement a little bit

Space slowdown is now 1.5 (same speed as a fat person in the station).
Jetpacks will speed you up by 2.5 (which, assuming you aren't slowed down by anything, gives you -1, which is the old space speed) and everything else is unchanged (including the slowdown for having stuff in your hands).

For movement delay, higher numbers make you go slower.

mspeed is movement delay, from what I can tell.
