Updates

Multiplayer has gotten some improvements for the newb experience including:

• Dramatically less spammy login, especially as a guest.
• Guests can't wander off into chargen.
• Better instructions

Added kangaroo infection, just need to slip it in somewhere, yay! Has about four new mutant powers.

Gryphons got LactAid mutant power, healing that gets more powerful with increased breast size. Who can argue?
