Massive reflection overhaul
Moved all classes to new package,
me.pagekite.glen3b.library.bukkit.reflection
Added SafeReflection, which (WIP) wraps exception-throwing reflection
calls and returns null in case of error
Added InternalPackage and SubPackage, which represent CB internals
Added PackageRepresentation interface, which represents a Package, and
will be used in the future for getting CB classes more easily
