Sane Filenames

I’ve changed from using the entry ID for the filename to using a "dirified" title.  Redirects should be in place so that all the old links work but if you do find an entry that has disappeared off the face of the earth please let me know.

Also, major apologies to anyone who winds up with every entry in my RSS feed being marked as new because of the change.  I would have hoped that wouldn’t happen but NetNewsWire seems to think they’re all new so I suspect the planet aggregators might as well.  Sorry!
