v1.0.2 Crate fixes

This is a small update the improves the feel of crate pushing.

• crates move twice as fast, and are quicker to start moving.
• the knight’s hitbox has been reduced and repositioned to reduce the chance of accidentally pushing a crate.
• it shouldn’t be possible to push a crate diagonally from an odd angle anymore.

Also, the timers for the restart and quit buttons have been reduced by half.
