Bug 30358: Strip leading/trailing whitespace characters from input fields when cataloguing

This enhancement adds a system preference StripWhitespaceChars which,
when enabled, will strip leading and trailing whitespace characters from
all fields when cataloguing both bibliographic records and authority
records. Whitespace characters that will be stripped are:
- spaces
- newlines
- carriage returns
- tabs

To test:
1. Apply patch and install database updates
2. Go to Administration, system preferences, find the new
StripWhitespaceChars preference. It should be "Don't strip" by default.
Change it to "Strip".
3. Search for a biblio record and edit it. Put some leading or trailing
whitespace characters in input fields and textarea fields and save.
4. Confirm these characters are removed when you save the record.
5. Repeat steps 3 and 4 for authority records.
6. Confirm tests pass t/db_dependent/Biblio/ModBiblioMarc.t
