install and update all bundles

honza/snipmate-snippets failed to update, though, because it’s 404 all of a sudden: https://github.com/honza/snipmate-snippets/ . The other version of snipmate-snippets out there, by scrooloose, is 2 years old, so I don’t want to switch to it. I’ll just stick with my current version, and hope honza eventually gets their repo back up.
