Add reader xml for DICOM reader.

Added two entries for the reader, which has two modes to load data. The
first mode loads a single DICOM file. The second mode looks at all files
in the same directory as the selected file and load them as planes in a
3D image.

Fixing problem importing other scripts in the main Catalyst script.

Introduced an issue where a Catalyst Python script trying to import

that reads the file.
