WIP: Add file loading

Now files sent down from the host are added to the slicer dicom
database and they are auto-loaded into the GUI for processing.

TODO:
- figure out why seriesDescription is not copied correctly to volume
node.
- process the resulting data and save the results to dicom files that
form a new series associated with the proper study
- send these files back to the host
Merge branch 'master' of github.com:pieper/SlicerDICOMHosting
