This update features a complete rewrite of the structure system, from the ground up, and eliminates the dependency on WorldEdit!

Some details about the new structure system:

• Spawn criteria are more strict - This will prevent structures from spawning in the ground/over caves as often.
  
• Structures are now stored internally, and loaded using Vanilla Minecraft's structure system - This drastically increases performance, since WorldEdit was extremely laggy.
  
• New config options - This version adds config options for the weights of structures. Higher values for weights mean that the structure will be "chosen" more often. - Mathematically, the probability that any structure will be chosen is weight/sum(weights)
  
• Aether and End structures are calculated separately, hence why they are grouped separately in the config.

This update also fixes #6
