New "Add Filter" Dialog

[cn187]

If anyone is interested in seeing/testing the new "Add Filter" dialog, I've just committed it to my dev branch (cn187_devel).

It's a bit busy, 'cause there are a lot of fields. But I tried to make it as user-friendly/intuitive as I could, given the complexity.

Bug reports and/or usability feedback/suggestions appreciated.

Compiling now... will report back. Devel build has been rock solid for days at a time. I think I've had one seg fault during a multi-week run.

Nice, thanks. If you can enable core dumps and get me a backtrace when that segfault happens, I can try to fix whatever it is. The last crash I had personally turned out to be the same bug as the Eye-of-Zomm issue. But I haven't been playing a ton, either, so...
