Added rudimentary creature stats.
Placeholder zombie sprites.
Not sure why he doesn't work with AnimationManager yet.
Testing more
Fixed RedZombie, moved stats around a bit, fixed (?) a NullReferenceException when exiting ActionMenus.
Made a barebones global gamestate tracking sorta object.
Restructured directories (sorry.)
Also added global objects for stats, items etc.
Replaced a lot of public variables with serialized private ones. Left some public, because it was simpler than making getters and setters.
