Towards #874

* As necessitated by the meaningless tracker blocker check
  in Panopticlick using a “simulated tracker domain” that
  begins with “tracker”.

It looks like the stats for a regular local inquiry
were based on the previous inquiry that used the
news sites domains.

Simplify rules on Wishabi sites (Flipp). Update index.

Added an empty line to the ends of all tracker entries so that the resulting HTML will properly close off the list in the Notes section and validate. Closes better/builder#99. Progress towards better/themes#156.

Transformed existing content to use the shorthand Blockdown format whenever possible. Related to better/builder#103.
