Dev Branch Created

Here there be drag- I mean bugs.
Switch to subterrain base engine

Huge performance increase and error reduction.  Also fixed stalagmite
and stalactites spawning in midair.   UNLIMITED vertical chunks.
Fix Typo

The jig's up.
Fix biomes not shifting correctly

Cubes may be symmetrical... but I'm not stressing.
Merge pull request #4 from HeroOfTheWinds/Dev

Version 0.3 Release
Fix declared version

No longer in the Dev branch, is it?
Bug fix (falling nodes)

Without this fix falling nodes (e.g. sand) do not work correctly. For example, placing sand on top of water the sand will drop and disappear.
