JSON File Output forwarder

[toschneck]

To be able to read out the Sakuli test results from the admin UI, write out the resulsts as Json to log.folder/result_<timestamp>.json. It be should be enabled by default

Also add all Sakuli/Sahi action to the json (maybe as sorted sublist in TestSteps, see RhinoAspect.java)
Bsp Log: Region.waitForImage() - wait for image for x seconds with arg(s) [gedit.png, 10]
Json vorschlag:

{
  "object": "Region",
  "method": "waitForImage",
  "arguments": ["gedit.png", 10],
  "message":"wait for image for x seconds",
  "documentation":"http://consol.github.io/sakuli/v1.1.0-SNAPSHOT/index.html#Region.waitForImage"
}

Modify the log output maybe to: Region.waitForImage(gedit.png, 10) - wait for image 'gedit.png' for 10 seconds

currently Dateformats aren't unified:

creationDate: "2017-10-04T15:49:31.689Z"

but stopDate or startDate:

"Oct 4, 2017 3:49:56 PM"

also the dateformat in filenames is different (but thats ok for me).
Using ISO-Dates everywhere would be nice since it's pretty easy to use in Javascript :)

@joroboro can you change this?

Issue with method dragAndDrop if arg is an Region object itself
