Fixes #23, although this means all sprites in pre-existing levels just
got their animation technically flipped. Need to go through Spooked and
Debug world and unflip them.

Fixed small issues where Edit Sprite Dialog opened in the corner of the
monitor, sped up Edit Sprite Dialog so it runs at the same speed as the
game when previewing a sprite, and finally fixed a previously unfound
error where having 'Edit Sprite' mode in the editor and switching
screens would not keep the sprites on the new screen frozen as they
should have been.

Updated .jar
Fixed a few more issues regarding opening the Edit Sprite dialog from
'New Sprite' not centering properly, and trying to click where multiple
sprites were suddenly stopped working since last implemented a while ago
(although it still needs some work to be nice at least it functions
now).

Rolled out the rest of the sprites in Spooked including the Bonus Doors
and Exit Doors (will need to check for any missing sprites in
playthrough) but Bonus screens can not be finished due to issue 26.

Updated .jar
