Ice Crystal Caves and Trees

Adds a new ice crystal cave underground minibiome, in which you can find Ice Crystals, which are necessary to craft Geometric items but cannot currently be found legitimately in Vanilla. This minibiome is just as rare as all the others.

Also tweaks an existing type of tree (dubbed "geometric" in the files) to drop Ice Crystals to match another existing tree that drops Crystals. (Note: this mod changes the color of the tree foliage. If you don't like this, just go into the mod's /plants/trees/geometric/stem folder and delete all the .png files contained therein.)

To install, just unzip in your ~/Starbound/mods folder

This mod will conflict with any other that modifies planetgen.config, like Variety is the Spice of the Universe.

If you want to use this mod and a mod like that in conjunction, all you have to do is remove the planetgen.config found in this mod's folders and edit the other mod's planetgen.config to include [ "icecrystalcave" ] in the three "detachedBiomes" sections.

Please let me know if you encounter issues with this mod (include your OS and the error message) so I can address them.
