New static files system
assets.qtpl is no more! Now you can just add files to static/ folder,
make sure the extension is registered in static.go (a shortcoming
that'll be addressed in future Go versions), and you're done! It
searches the local file system first, then falls back to the files
embedded with the binary (in the static/ folder).
