Bug 15966: Move MARC frameworks actions into a drop down menu

Bug 15966: Move MARC frameworks actions into a drop down menu

EDIT: Switching icons for Export and Import. What I had initially was what I intended because export is like downloading and import is like upload, but it seems to make more sense reversed.
EDIT2: Fixing Import problem

To test:

1) Go to Administration -> MARC bibliographic framework (admin/biblio_framework.pl)
2) Confirm that all actions have now been moved into drop down menus.
  a) For Default framework, actions available are 'MARC structure', 'Export' and 'Import'.
  b) Confirm these buttons all work as expected.
  c) For all other frameworks, actions available are 'MARC structure', 'Edit', 'Delete', 'Export' and 'Import'.
  d) Confirm these buttons all work as expected.
