Experimental build: some random small things

I spent a good chunk of the week rearranging all of my code (in the way that you can’t really perceive from the outside). Still, there are a few new things in this build:

• Fen’s stomach uses a new system for bulges. It’s the same thing used for its tail and breasts. It should behave a little better than the old physics-based system.
• You can now drop things after grabbing them.
• Gryphons can grab things!
  • In the future, they will be restricted to grabbing small things
• Non-humanoids can be grabbed and eaten
  • There are no non-humanoids yet
  • This is how items will work, though!
