merge 4.0.0
Refined design of download panels, moved terms and conditions into specific section of page so that it is more obvious that the terms are for the downloads, not for the whole site.
Added a hover affect onthe accept button plus a glyph icon to help indicate the terms and conditions still need to be accepted before a download can take place. All should work in  no script browser.
