jjmpeg 3.0 released

Put enough together to push out a release of jjmpeg.

It ended up 1700 lines of Java, 2000 lines of C, and 300 lines of Perl.

Apart from supporting the latest version of FFmpeg (at least when I started a couple of weeks ago), it's smaller, cleaner, and more complete than any previous version. Having said that this is essentially just a beta release.

This one is licensed GNU General Public License Version 3 (or later).

I've kinda had enough for the moment so it's a pretty bare home page, but it's there.

Merry XMAS!
