Subject: [PATCH] Bug 37143: Do not allow required fields with only whitespace
 to be submitted

To test:
1. Make some fields for OPAC self registration required.
2. Create a new patron via self reg.
3. Fill out those required fields as an empty string like "  ".
4. Submit the form, it succeeds.
5. APPLY PATCH, restart_all
6. Try again. Required fields with only whitespace are treated as if they were empty.
