v1.0 beta: Networked game, maps ratings & more

New version 1.0beta finally released!

This means:

• Network matches! Play with your friends over LAN  in 3D or 2D mode. Using Tunngle or Hamachi, you can even play over long distances, assuming the Internet connection is good enough (preferably < 150ms).
• Map rating system! You can now rate maps while you play them (in the pause menu), and sort maps by rating.

...and various other improvements. See for yourself!
