bug 9370: improve splitting of LC call numbers for labels

Use the Perl module Library::CallNumber::LC to parse and split
LC call numbers when generating spine labels.

For example, QH541.15.C6 C25 2012 should be split as follows:

QH
541.15
.C6
C25
2012

To test, create an item with call number QH541.15.C6 C25 2012
and classification source LC, then create a spine label for that
item using a layout of type 'biblio' that has the split call numbers
option enabled.  The call number should be split as indicated above.
