Amendments needed prior to going live

Corrected file extensions of all posts to .md
Moved unpublished posts to the _drafts folder
Updated links.yml to match the rest of the network
Updated the authors.yml for the same reason
Revised post categories so the trip is at the end in case we visit places again
Also set redirect pages for the trips i.e.
      /china/beijing/china-2009/ redirects to /china-2009/
Updated CNAME file with live site domain
