hft.org restructure
- integrated blog posts directly into the body of the document (previously there had been some cut-n-paste happening)
- separated out and cleaned o-blog admin and technicals, which are now all contained in gh-page production section.
- aligned README.md and about.html to remove redundancy (subject to pandoc conversion from md to org, then org to html).
Added NEWS to README.md and a post
Also missed an old tangle
added news and zipline post
Ripped technology stack info out of README - as it's rapidly evolving, best to bring the information back into hft.org.
