created a "writing floppies" howto on the wiki

Hi guys. I made a thingy.

http://gamesx.com/wiki/doku.php?id=x68000:writing_floppies

If you guys want to fill in some info for winmac that'd be great. I don't run either so I don't feel like I should be writing the documentation in case there's anything additionally special that needs to be done, gotchas, whatever.
