XUProxy status update

[andrew_w]

I was way too optimistic in my previous post about how long it would take, but I have now finally completed the unit tests (it's a good thing that I wrote some unit tests, because I found several major bugs in the filtering engine using them). I also added a few more minor features.

I will release 0.1.0 shortly (hopefully for real this time). I just want to test the filter on a few more actual sites first. Anybody who wants to try out 0.1.0 before I release it can download the sources from the XUProxy Mercurial repository on SF.
