Ability to export & import.

Add the ability to export and improve from/to a JSON file that represents the:

• results (table)
• microprofiler data
• graph data
  this will also include the stats like Avg, 10%, etc.

Could also do what Benchmarker does and save the data as an attribute, and then also show previous runs (with a hash of the code to tell if it is an older version) to preview.
