Bug 19267: Rancor - Warn before leaving page if record modified

To test:
1 - Open the advanced editor
2 - Make some changes to a record
3 - Click on 'Patrons' or leave the page in some way
4 - Note there is no warning and changes are not saved
5 - Apply patch
6 - Open the advanced editor
7 - Make some changes
8 - Leave the page
9 - Note you get a warning of unsaved changes and can stay on the page
