Lots of new wiki stuff.

[Lawrence]

There's a stack of new pages on the wiki.  

It's now officially the home of the GameSX pages.  I've started deprecating old pages and pointing them to the new page on the wiki.  Links from the main GameSX index are going to link to the wiki instead of the old GameSX pages.

GameCube Digital Audio
GameCube Digital AV Port
Jaguar 50/60 Hz
Capcom A10CA Power Stick Fighter
X68000 6-button controller

Several people have been adding pages to the wiki lately, and for that I'm grateful.  Keep up the good work!
