Hitbox script index page

Here's a list of all the games that have working hitbox scripts. It's a nice public page so you can link it anywhere.

A big commit brought all the scripts up to date.

Should have done this a long time ago. I guess this stuff could have been put on its own page from the beginning instead of with MAME-rr. In any case it's good that they are in a versioning system, so people can track changes and get updates if they want.
