Bug 1421799 - [mozlog] Improve the 'mach' formatter r=gbrown 

This makes several changes to make the 'mach' format cleaner and easier to
read. Some of the changes include:

* No longer print the 'action' no matter what. Printing the action for things
  like 'log' or 'process_output' was redundant and caused verbosity. Now this
  is done on a case by case basis (things like TEST-START/TEST-END will still
  have their actions printed).
* Color coded the process id for 'process_output' actions. This is a dim cyan
  to avoid conflicts with other actions.
* No longer quoting 'process_output' messages
* No longer printing thread information. In 99% of the case, this was just
  dumping 'MainThread' over and over again. Perhaps printing this could be an
  option on the formatter.
* Muted timestamps to help the important parts stand out better
* Colorized suite summary headings
* Unexpected statuses in _format_expected() are always red (never yellow).
  This is to help make it stand out from all the other yellow text that gets
  printed.
* Internal cleanup/refactoring
