WhosOn User Tracker 2.2 and WhosOn Monitor

I got the next version of WhosOn User Tracker ready. The old way of updating the distributed tracker was scrapped and moved completely to web services. I have been testing this method of tracking on several sites for a few days and I haven't really noticed a slow down.

Also, for clarity's sake, I have renamed WhosOn Tracker to WhosOn Monitor. It's a little more descriptive and also it helps to tell the two projects apart.

Maybe one day I will actually get the Monitor finished up.
