Update Mappings for 152
Rework ClassPath to UserLibrary. Easy to add extra mods without specific lined dependencies for each.
Fix obfuscated name issue. Entityliving age name is incorrect.
Remove data dependency of static spawner classes. Hypotehtically this reduced any chance of concurrency issues if multiple world update loops are called in different threads. Not convinced this is neccesarily a problem, but was poor practice non the less.
