Fix spawn crash caused by gravity code in select screen.
Update running code:
running {speed} {height} {length} {move} {land}
{move}:
0 - can't run up/down
1 - can run up and down diagonally
2 - can start running by inputing uu or dd
4 - can turn 90 degrees while running (like in some capcom games)
3 = 1 + 2
7 = 1 + 2 + 4
And so on
