File Transfer History should allow to filter transfers that do not include files

Current Behavior:

• The File Transfer History view logs entries for any transfers. This includes transfers that did successfully copmplete without transferring any files. This creates a larger number of unnecessary entries in the File Transfers History. for users who perform polling for files.

Desired Behavior:

• The File Transfer History API offers a property to prevent transfers that do not include filess from being reported.
• The GUI offers a checkbox accordingly in the File Transfer History view.
  • The default value of the checkbox is specified from a new entry in the "joc" section of the Settings view.
  • The current value of the checkbox is maintained throughout a user's session in JOC Cockpit.
