Bug 17364: Add ability to exclude some columns from selection for system preferences

Bug 22844 Added the option to provide a modal for selecting database columns for system preferences

Some system preferences are limited to a subset of the columns allowed. For instance, setting branchcode
in BorrowerUnwantedFields prevents adding new patrons

This patch allows for defining exclusions in the .pref file

To test:
1 - Alter BorroweUnwantedFields and select branchcode
2 - Attempt to add a new patron
3 - Get a message like "Something went wrong. Check the logs"
4 - Apply patches
5 - Alter the preference again
6 - Note that branchcode is unchecked and disabled
7 - Save the pref
8 - Add a patron
9 - It succeeds
