ENH: DICOMListener with optional indexing, specifying port and incoming data directory
- added possibility for: -- defining directory for incoming data -- incoming port (default: 11112) -- enabling/disabling indexing by providing dicomDatabase (True) or not (False)
- improved error handling and feedback for user
- when no dicomDatabase specified, incomingDir is required, otherwise an UserWarning is raised
