So, I've decided to maintain the mod as a seprate entity from Xeno's Reliquary until I get permission to continue the offical mod, or I'll stop when Xeno comes back from hiatus and picks up developement again.

 Versioning
 =========
 
-The mod currently is at v1.6.4-1.0. This is a direct port of Xeno's original commit to 1.6.4. I'll be adding stuff from later commits where I see fit, and will also being adding new features under a eventual v2.0 milestone. Version numbers are independent of MC versions, and MC versions are included solely as a convenience.
