Wrote a whole lobby app

Current issues:
- Clients only know about users who join later (easy fix)
- There's a weird shadow that follows everyone around and I have no idea why

I may have broken internet play by changing a line in cmenudp.py so that it no longer sends to 12801 and instead actually pays attention to the IP it's supposed to be sending to. It should work but feel free to revert.
Added sprite file which was not included in the previous commit
Fixed a number of bugs

- Player movement now actually works
- Fixed player duplication on connect
- Fixed doppleganger bug
- Commented out and removed some print spam

minor
