Download link on homepage points to confusing location

[hadley]

It's confusing that the download link from http://getbootstrap.com/ downloads a zipball of the repo, rather than the release distribution (as pointed to from getting started: https://github.com/twbs/bootstrap/releases/download/v3.0.0/bootstrap-3.0.0-dist.zip)

If you think that is the correct link, it would be useful to give it a different text so that two "download bootstrap" buttons don't point to different lengths
