Use JobIDs to keep Link References

By default, you will loose any reference to links that were added as a result  to a add linkgrabberv2/addLinks call.

However, there have been several requests to keep this reference alive and use it in the linkgrabber AND the downloadlist.

1. add {..."assignJobID":true...} to the "linkgrabberv2/addLinks" call
2. JD will return a {"id":15387128376} object. "id" is the JobID
3. add {..."jobUUIDs":[<JOBID1>,<JOBID2>,...]...} to the linkgrabberv2/queryLinks or  downloadsV2/queryLinks call
4. the queryLinks methods will return all Links that result of the JOBIDs you sent
