LP#1501781 - Make patron name search diacritic/space insensitive.

Diacritical marks may exist in the patron record -- as they should, but this makes patron name search difficult
for librarians who may be unfamiliar with all the special characters used and also how to elicit them from a
keyboard.  To ease this, accented characters will be converted into their 'plain' analogs for comparison purposes.

So, for example, if the patron's last name is Chávez, typing "Chavez" in the Last Name box in Patron Search will
match it.

Spaces in a name (like "De la Croix") will be squashed out so that name would be matched by "Delacroix" or "De la Croix" or variants.

The librarian can enter the accented characters or not.
