HTMLCS command line changes, primarily for reporting.

1. Responsibility for tallying the messages is sent to the outer file
(HTMLCS_Run).
   .. The inner file will now produce log messages starting with
      "[HTMLCS] " which will be suppressed until the end (except for the
      "done").
   .. Report will be produced at the end when "done" is called.

2. Added an extra report type, which shows the report in a neat table.
   .. Add extra parameter "table" to switch to this.
   .. By default it will continue to use the "pipe" format, with the
      extra two fields now added (for node name and ID).
(TODO: modulising something like this.)
