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/
Ah! Sorry, I forgot to uncomment them before commiting. I disable the Github buttons while I'm testing as they take some time to load - I know its just a second or so, but when you're used to instant livereload even that feels too much.

I'll try to be a bit more cautious from the next time :)
