Converted HccRegister into new reporting format.  Need to investigate performance implications in the same manner as the ArtRegister with the visit columns
Re-implement chronic care register using new reporting constructs.  Address a few new requests, including:
* Adding Chronic Care Number
* Adding patient id
* Removing national ids
* Adding the "Source of Referral" as a column
* A few bug fixes were also discovered and fixed from the previous version, notably that the most recent visit did not limit to the end date of the report.
Add back in the ArtEncounterExport as a new ReportDefinition
Initial work for chronic care visits report, but very incomple and not yet turned on.
