Moved some of the operations around, but mostly I just added some
documentation for this release. Due to the fact that lama is not a full
game and lacks "character saving," hotbooting is a bit lacking. Preserving a
mob is basically impossible, due to the nature of a hotboot, so I won't even
try to do it here. Instead, once you implement some kind of player saving
and loading, use that before and after the hotboot. Saving the player
characters in the main.lua game loop, around where clients and servers are
saved, and loading them in Game.onHotboot(), just after the players are
recreated.
Added log directory.
