Get event ordering right while generating PHP screenshot
Added option to dump PHP html (+ revert recent changes for now)
Add options to dump computed CSS for each screenshot

* Now, can dump a subset of computed styles for "all" elements
  in json format in a <script> element in the head. The output
  is sorted by node-name to possibly compare css via 'diff'.

  --dumpPhpCSS and --dumpParsoidCSS are the new options.

* Also enabled logging from the webpage to get to node console
Fix span.reference styling to match PHP styling

* We have font-size:smaller and PHP css has font-size:80% and that
  seems to cause a 1px font-size diff in chrome (and phantomjs),
  but no diffs in Firefox.

* Will push a core parosid css fix to match this.
Change default port of diffserver to 8002

* Visual-diff RT testing seems to be using 8002 for the @lh link
  -- makes it simpler to start and use the server locally
  without having to use the -P option.
Move extra styles for parsoid content to a yaml file
Merge pull request #4 from subbuss/yaml_styles

Move extra styles for parsoid content to a yaml file
Remove hardedcode path to styles.yaml file

* Lets us run diff service, commands from different directories
  and experiment with different style settings, if useful.
Use URI encoding to escape special chars in file names

* We are having problems with utf-8/non-utf-8 encode fo file paths
  on ruthenium. So, this is a good workaround which also handles
  the presence of "/" in titles.
Use a handlebars partial to render the summary text

This adds a parsoidRTConfig file that just sets up the partial.
