Message: Frustum culling added to make the game run faster! Basically this just 
means that whatever is on screen isn't drawn or animated any longer.

In cavemap.lua it was tanking a little in the FPS with all the new models added 
for walls and rails for the mine carts.

Here's the numbers on cavemap.lua from my machine:
Without frustum culling - 99fps without vsync, 56-60fps with vsync.
With frustum culling - 380-440fps without vsync, solid 60fps with vsync.

As we move further, optimizations will be harder and harder to do, but this was 
a really low hanging fruit, and there are a few more left before it'll get 
difficult (:
