2.2.1 ready for alpha release

Well, its all working, I just need to update a few html and script files for the release.

This will be an alpha release, 'cause there were just so many changes. But you gotta use it. If no one finds any problems, it will become beta. (I'm considering keeping the alpha designation for 2.2.2 as well, as that involves more deep changes.)

Note that 2.2.2 will speed updates a bit more, as well as increasing reliability, by moving transactions to the command level where they belong.
