Bug 4340 - patron name search does not handle punctuated names

This patch will enable C4::Members::SearchMember to handle searching for punctuated
names (e.g. the "Jones" in "Smith-Jones" or the "Angelo" in "D'Angelo")

It is possible to add a bunch of LIKE clauses, but that adds to the search time in
a rather dramatic way.  REGEXP, by itself, is also a performance killer, but I found
a suggestion of using a more-general LIKE ANDed with the specific REGEXP, and this
gives excellent performance over other approaches.
