Maintainance release 0.2.1 is out

Both MARF and SpeakerIdentApp "experienced" 0.2.1 release due to a small bug in the app, missing files in the previous distro, and somewhat out-of-date doc. files in places. This all believed to be brought back up-to-date with 0.2.1.

The app also includes marf-0.2.1.jar within itself (the -bundle and -bin tarballs) just to make it possible to run it almost "right out of the box" with one download.
