Get rid of a couple of copies of the CC0 text. Add header comment to
CC0 files to remind people editing them what the terms are. Also add
some missing XML headers. The header comments in layouts won't bloat
the binary - they get stripped out before compressing, same as any other
comments.

also split the ekara software list up a bit so they're easier / more logical as different carts are meant for different devices; the popira unit can use the 'GC' carts for example.
Dance Dance Revolution Family Mat and Popira are actually playable, but until I fix the timers in the driver the music is half speed like the e-kara stuff, and because these are music games, they're being eft as NOT WORKING until I sort that out.
