Error message for save order when dcm4chee is not online, Modality enum
changed to display full names of the dicom acronyms, internalization to
remove the hl7message bug that was coming up randomly. Included
privilege for radiology patient dashboard in config.xml. UI fixes for
orderdate/appointment date, check if order is completed before adding
observations.
