make contact id column available to display in reports

We get asked fairly frequently to add contact ids to reports (as available fields). It seems a bit awkward because the field is displayed buty hidden & seems to take up more time that it deserves. I just used this patch to add the field to the 3 detail reports - I can commit if this is OK.
