Condense the action log into a scannable table

Several minor improvements to the action log presentation:
* Now a table with date and human readable presentation as
  rows is displayed
* If no changes in a title were detected, the old version
  is omitted
* The "inferred" flag is demoted to the end of the line
* You can zoom in on the node's history directly from a
  log line
* byline for the first publish action is preserved
* Revisions are directly linked to when a new one i
  published
