Skills gui no longer pauses game

This is more consistent with vanilla behavior (e.g. inventory) and also
no longer triggers a game save
Fixed errors in EntityHookshot write/read NBT

hitX/Y/Z are double values, but were saved as shorts, and loaded from
the incorrect tag values.
Fixed range of items sending particles packets

Changed to 64 block range (about the maximum range particles can be
viewed), rather than 4096
Made AntiqueAtlasHelper methods static
Fixed order of items in creative tabs

Items and blocks are now sorted in order of their declaration in the
class, regardless of their order in the game registry.
Also implemented all creative tabs class as static inner classes to
ZSSCreativeTabs.
