Hotfixes and Undo Button — Wyrmicide Steam update #468240

Special thanks to Nievano on Discord for the bug reports and suggestions! Fixed summoning pieces in single player. Fixed health bars in multiplayer combat. Fixed Scorpion gaining a charge from being hit by its own reflected projectile. Added button for undoing item purchase. As of now, the undo button only resets your item purchase. If you move a piece, your turn is immediately sent. Undoing movement will require clicking a button each turn to confirm. Let us know what you think.
