Journey to the Center of Hawkthorne v0.0.81

Greeting Hawkthornites, it's release day again!

Today's release includes:

- 25 new costumes
- Poker bug fixes
- Small updates to the Greendale campus including Jerry the Janitor NPC
- Less annoying hippies in the hallway
- Inventory redux: now able to drop items by pressing 'esc'
- Exiting from overworld puts you at the right place on the map

I (Derferman) have recently started a new job, so I haven't had as much time as I would like to dedicate to the game. A huge thanks to all the devs who have taken up the reins in my absence.
