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

Here there be drag- I mean bugs.

Use the CLUSAV and CLUSAM constants at the start to adjust.

Slight conflict of ideas with another mod.

Manual merge of Zeno-'s changes, with several revisions.

Lots of values moved to config.lua, split nodes and functions into their
own files.

Added Glaciated Biome

Added craft recipes for Mycena Essence, Glow Mese Crystals, and a
reverse recipe for them. Fixed selection box for mycena mushrooms,
adjusted crystal variation rates.

In other words, mesecons-users will be pleased.

Also increment version number in the code.

Apparently I think everyone has 20-20 eyesight.

Mycena mushrooms, glow worms, giant mushrooms, slight biome logic
cleanup.

Credited Zeno- for his help

Approx. 300% speed increase

New crystal color and two more additions: lichen covered cobble and
fungus.

No testers were impaled in the making of this release.

Began moving values to config.lua so they can be specified in the .conf file

New crystal stalagmite structure, now generates stalactites.  Some
setting tweaks.

Preliminary release for v. 0.2.
New glow crystal texture, stalagmite generation added.

This ain't no Cave Story.
