I've migrated my blog... again!

It seems I migrate my blog more than I update it, but I have once again. I got fed up with Heroku, and wanted a VPS for other projects anyways, so I bit the bullet, bought a VPS from Linode, and rewrote everything. I'm now using the amazing fabric library to statically generate my site and upload it to a VPS running nginx. I was even able to reuse most of my old code! Not that many people read this thing, but for the few who do, loading times shouldn't be > 10 seconds anymore (Heroku's free tier is seriously terrible for low-traffic sites). Besides that, everything should be basically the same, except that I also improved the RSS feed to actually validate.
