Added note item

Note item can store up to 256 characters of text. Blank notes are
writable and notes with text on can be torn up but not edited. Added to
all loot spawn indexes as a common item and added a few default messages
with the option to expand via the settings.json file.
Tutorial fixes and bleeding animation fix

Bleeding animation now works when on foot instead of only when in a
vehicle.

Fixed tutorial option button not being hidden when spawning.

Fixed tutorial items not being deleted when a player exits the tutorial.
