Marcel de Rooy 18f4a89ce6 Bug 19096: Do not allow changes to kohafield within MARC frameworks 
This patch makes two changes in the script for managing the MARC
frameworks in order to support making the Default authoritative
as for Koha to MARC mappings:

[1] Disable the kohafield select combo. Add a hidden input to save value.
[2] When a new subfield is added, the kohafield is still empty and should
    be overwritten with its Default counterpart.
    Note: Although we could leave the field empty, since Koha looks at the
    Default framework only, it does not cost much to keep these fields in
    sync with Default and perhaps catch a bug when someone somewhere looks
    in the wrong framework.

Note: The description of Koha to MARC mapping on admin-home has been
adjusted accordingly (removing last two lines).

Test plan:
[1] Add a new tag and subfield in Default.
[2] Map it to a kohafield in koha2marclinks.pl
[3] Add the same tag and subfield in another framework.
    Verify that the kohafield is updated after you saved the subfield.
