Bug 11826: Use XSLT handler object in showmarc, Record.pm

Modifies showmarc and opac-showmarc to use new XSLT handler.
Removes cardview.pl as obsolete script.
Modifies C4/Record.pm and a typo in the test Record.t.

Test plan:
[1] catalogue/showmarc: Go to Cataloging. Search. Click Card.
[2] opac-showmarc: Go to opac detail, MARC view.
    Open URL for plain view in new tab.
    Change URL: Change viewas=html to viewas=card
[3] Verify that there are no references in the codebase to cardview.pl
[4] C4/Record.pm: Run the Record.t test in db_dependent.
    This test uses marc2modsxml, triggering the change.
    Additional: export to MODS from opac-detail.
