Status Effects And Magic

NEW STUFF:

• Added Help Screen with game mechanics explanations (very much a wip, and will be expanded and rewritten as more mechanics are added).
• Fully implemented 3 status effects (stun, burn, and poison).
• Consumable items are now marked with a special symbol in their description.
• Implemented magic system with spell tomes and staffs. Currently only one spell is available.
• Added a new mimic enemy (design not final, made mostly to showcase status effects ).
• Added new items.
