[1.0.0-alpha1] Floor up and down hotkeys now go through all 9 floors.

[tulip wolf]

The Floor up (E) and floor down (Q) hotkeys now go through all 9 floors. When on the top floor of a space floor, floor up key will now go to the bottom floor of the next higher space floor. Same for floor down in the other direction. The floor up and floor down arrows on the right side of the screen still work as they used to and only go through the 3 floors on the space floor.

If this is intentional, please make it configurable.

Either way, the buttons should do the same thing as the hotkeys.
