Fixed #178

Improved the Chrome profile clearing (mostly matches Telemetry now), added in more default command-line switches for Chrome and added support for closing all running instances of Chrome.
Changed the default timeout to 2 minutes to match the desktop default
Added support for running multiple pre-configured browsers on the same device (Chrome and Chrome beta currently).  Requires that the "brwoser" name either be "Chrome" or "Chrome Beta" or end with "- Chrome" or "- Chrome Beta" and only kicks in if an explicit package isn't passed in on the command-line.
Added Chrome Dev as a known app, cleaned up the regex for running chrome processes and cleaned up some formatting.
more regex cleanup for matching running chrome instances from ps
