Foundation 4 download link is broken - use new version Foundation 5 ?

[alaindomissy]

The link to download Foundation 4 is broken; it should be replaced with :
http://foundation5.zurb.com/cdn/releases/foundation-4.3.2.zip

Also: the current version is Foundation 5. Should we use the new version?
Download link would be: http://foundation.zurb.com/cdn/releases/foundation-5.2.0.zip
Miration guide is here : http://foundation.zurb.com/docs/upgrading.html

I think we should use the new version of Foundation. We might have to take the screenshots again, but that should be easy.

Thoughts?

I updated foundation in #139, it can use screenshots though.
