* metaprogram.h
Created by Mr. Griffin. Removed non-relevant parts
* Added DEFAULT/DEFAULT_2 macros
Also added a demonstration in battle_main
* Removed GET_ARGS
* Expanded DEFAULT
Because why not?
* Added EXCEPT
Expands to everything but the first x arguments.
* Added BIT_INDEX (thanks to MGriffin) and COMPRESS_BIT macros
These let you compress a bit up to a word in size inside a single byte and uncompress at the same time. BIT_INDEX just tells you where the bit is.
* Updated HANDLE_EXPANDED_MOVE_NAME
