Integrating ability to read creature definitions

Should be working with a few changes to the server.

I also updated the existing maps to use the Flytrap creature definition,
since it's the only one we have right now.

I'm noticing a little glitch on spawns where the creatures don't show up
until after they move once. I'll look into that.
Fix for creature animation

Fixing creature animation and temporarily setting Flytrap to
non-aggressive so that I could test the aggro behavior. Will set it back
before the end of the cycle.

Also created the definition for hermit crab. Woop.
Integrating damage formula into the code

Damage formula is working correctly in-game now and dodge and crit are
being handled. Currently, dodge doesn't do anything or send any message,
but we can expand on that in the future.
Doing a project upgrade since it doesn't cause very many changes to the code base.
