Items for Tinny

[AntumDeluge]

Creates NPC "Tinny" & quest "Items for Tinny".

Closes #256

TODO:

• Create NPC Tinny.
• Create quest.
  • Much of the dialogue has been hashed out in New NPC Tinny #256, but the reward should be changed since there is now another quest that already increases bag size.
• Create unit test(s) for NPC.
• Create unit test(s) for quest.
