Add support for Outputting Autogenerated Test HTML

This commit introduces two flags, '-g' and '-o' to
the `run_from_console.js`.  Both flags do not run
the tests.  Instead, deal with the autogenerated
HTML.  The former outputs the paths to the autogenerated
HTML temp files, and then pauses the program until Ctrl-C
is pressed (or SIGINT is sent).  The latter outputs the
generated HTML for each files to STDIN with the names
of the tests to which they belong.
