Move Prefix field ahead of Names in patron editor

Move Prefix field ahead of Names in patron editor

In earlier versions of Evergreen (1.6 and earlier), the Prefix field
was used to enter title information, such as Mr., Mrs., etc. When the
field was eventually added to the newer patron registration screens
(2.0+), it was added before the patron's last name field. Ideally,
the prefix should be listed prior to the patron's first name instead.

In addition, address label issues by changing "Suffix/Title" back to
only "Suffix" and making "Prefix" into "Prefix/Title".
