Split release notes into multiple pages

[ketan]

A single release notes page is now getting longer and longer, takes a long time to load.

Each tab has several images, all of which are being loaded by the browser, even if the user chooses to not see release notes for a particular version.

Hurts SEO — the current page has release notes for each release, but you can't google for individual things in individual GoCD releases.

I'm thinking of:

• www.gocd.org/releases showing the current release notes
• the page look and feel remains the same
• the sidebar links, instead of showing/hiding divs should navigate to different pages (www.gocd.org/releases/GOCD_VERSION)
