Build 0.1.2 and 0.1.2.1

Added a new art for the ghost coin courtesy of Aniriaram.

Saving should now work on all platforms.

Saving now saves all of your stats, inventory, gold, and the enemy you are fighting.

Because dying would now essentially brick the game I added a respawn button which will reset your level, health and the enemy.

Removed build 0.1.2 because of an unexpected bug where you will have no stats if you have no save file and to add respawn button.

Edit: The in browser version still doesn't save. I am not sure how to fix this problem.
