Downloads Page

There are still a few things left from comments on #1 that need to be addressed. I'll probably add commits here...

I have deleted my fork, so all changes are now live at: http://musicbrainz.github.io/picard-website/
We can remove the word website (it's sort of apparent :)). The title should also sufficiently describe the different pages, too, so something like "Downloads — MusicBrainz Picard" would work.
