Addressed one minor issue to clarify something in the tutorial stage, and fixed one game-crashing bug:
On the tutorial locked gate, when the use action is performed, added a textbox to let mages know they can use a spell to open the gate, and a thief know they can pick the lock.
Fixed a crash bug when the animation of the blacksmith beginning to hammer again at the same time the user tries to open the shop screen. The animation no longer blocks the engine GUI loading.
