Limit classes of concepts usable on the Problem List in the Patiant Dashboard

Not all classes of concepts should be allowable in the Problem List on the patient dashboard. It can lead to strange problems like TYLENOL, MOTHER, HALF, NUMBER OF WIVES, SCHEDULED VISIT, and CONDOMS just to name a few. The following concept classes should probably be allowed as problems (and perhaps others)...
Diagnosis
Finding
Question
Symptom
Symptom/Finding

It maybe be wise to have the classes to include in the problem list configurable as a Global Property.
