fixed configs and added description of what the variables do on the configs!
Sometimes ores form in air. This is a rare occurrence but tends to happen around water bodies.
May have to do with how Mc does terrain generation and when the server is overloaded. Still don't quite know how to fix this guys :(
default ores still spawn in about 25% of chunks. this is an issue with Bukkit's parallel task synchronization I think.
