Added A Ton

-Basic UI.
-Replaced Smurfs with goats.
-Added multiple animations.
-Added projectiles.
-Can shoot, damage, and kill enemies.
-Added nut collection up to 2.  No drop off yet.
-Various other things.
-Fixed rock spawning depth layer in a cheesy way.

-Need to fix stones/spawning spawning near start.
-Random monster spawning needs to be updated, disabled for now.
-Collision with tree is not working right.  Can walk through through
bounding box along X axis, but not Y.
-Collision with rocks is weird, can sometimes walk over them from
different directions.

-Look at my collision calculation rectangle, it might be messed up.
