finReportTemplateRO.Constants Property now available

To previously retrieve a Report Template's Constants from its read only object (i.e., finReportTemplateRO), the Function "CreateConstantsKeyValueList()" needed to be called. This wasn't efficient, as it was rebuilding the ISKeyValueList each time it was called.

This has been updated to a single "Constants" property, which behaves similar to the non-read only version. It returns an ISKeyValueListReadOnly object containing the Report Template's Constants.

The existing finReportTemplateRO.CreateConstantsKeyValueList() Function has been obsoleted and should no longer be used.
