Couple fixes.

- Add a "make clean" target that deletes various directories produced when locally building
the site.

- Clean the tree before "make lint". This removes any stale files from the public directory,
which is important since those can lead to spurious lint errors.

- Stop passing the no-longer-existing -minify argument to gen_site.sh.
