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
another Python script in the same directory was causing problems.
This was introduced with trying to make importing Python scripts
more efficient in parallel by having proc 0 being the only one
that reads the file.
