Browsertime 0.2

• Add --raw flag to control if data for individual runs is included in output.
  The default is to not include run data. NOTE - this is a change in the default
  output from 0.1.
• Add optional --compact flag to disable pretty printing of xml and json.
• Update format of xml/json (NOTE - incompatible changes from 0.1)
  • all metrics and statistics are now floating point numbers
  • numbers in json output are now represented as strings (surrounded by quotes). This is an
    unfortunate side-effect of avoiding printing numbers in scientific notation.
  • time property of marks and measurements have been renamed startTime
  • measurements and statistics are now sorted according to start time.
• Changed max wait time for the Selenium driver from 30 s to 60 s
• Updated org.seleniumhq.selenium:selenium-java from 2.35.0 to 2.37.1
• Fix for Firefox 25 that added toJson in window.performance.timings
