Wrapping up nodebloggy

I added linking by post title and the XML page. I was hoping to get a little work done on Dweller pathfinding tonight, but I'll be just as glad to have this closer to completion. I added timestamp (hey, everyone drives by GMT anyway, right?) and a little parsing of header to URL for pretty URLs - which is something I never had on d.net. I'm pretty pleased with myself, in all. :)

It'd be nice to get some image processing and a gallery and all that in here, but ... another time. Dweller beckons!
