Added most know definitions

Hi Merp,

This is most of the known definitions for AZ1G900C (except some of the latest alpha definitions).

The majority of the definitions were taken from here: http://www.romraider.com/forum/viewtopic.php?f=34&t=6769&start=22

The rest of the definitions were either taken from the relevant alpha thread on romraider or identified by me.

I know this would be lots of work for you to verify, so not sure if you want to just blindly pull them, but thought I would offer it up anyway.
