Switch to using Institution Program Code as the Unique Identifier in the Bulk Upload Process

In response to Dean Hieberts suggestion that the SABC Program Code is an increasingly obsolete code, and Institution Program Code is a more suitable identifier used to create a link between the program and each Offering in the Bulk Upload template.

Start by locating the bulk upload process and template references, then trace where SABC Program Code links programs to offerings. Done means the process consistently uses Institution Program Code as the unique identifier and the template and related behavior reflect that change.
