Bug 22124: Update cataloguing plugin system to not generate type parameter in script tag

Test plan:
1) Apply the patch
2) Have defined some cataloguing plugin which generates javascript - for
example dateaccessioned.pl
3) Go to cataloguing/adding item and show source
-> there should be no type parameter in script tag in code added by
cataloguing pulgin
4) prove t/db_dependent/FrameworkPlugin.t
