Bug 15699 - Course reserves instructors should be in form "Surname, Firstname" for sorting purposes

This patch changes the order of the name fields and adds a span class around
each in case of library wanting to customize further

To test:
1 - Enable course reserves
2 - Add some courses with instrcutors
3 - Note they are of form "Firstname Surname"
4 - Apply patch
5 - Note the change
6 - Note span tags
7 - Note you can hide firstname by adding to intranet user js: $(".instr_firstname, instr_separator").hide();

Sing-off note: This patch displays the names as advertised on cgi-bin/koha/opac-course-reserves.pl Sorting
the names would need some more actions but seems not to be intended by this patch.
