Changes
- More bird feather colors, to match the corresponding bird
- Macaw Baton has a new sprite, ideally this should better communicate it's difference from the sword
- New room in mango's lab! This should help tutorialize more of the bird's behavior at the start. You'll need to talk to mango to unlock the room if you already have a bird.
- New Auto-Save screen post logo!

Fixes
- Major cleanup of depth collision code. Interactions with birds / flintlock at a higher depth should make a lot more sense!
- Fix a lot of bird-related crashes, related to sitting on things
- Add more "null"-checking to the large canon, to further prevent crashes
- Birds you've collected should show up correctly at the lab
- Fix bug with mango's dialogue bubble when doing certain dialogue options in a funny order
- Remove random invisible walls from birds sitting on perches
- The third bird now correctly shows its price
- Remove extra explosion from the flintlock bullet that looked funny in certain situations
- D4 item now has a correct outline in the dungeon
