Bug 12675: Remove CGI::scrolling_list from labeledMARCdetail.pl

Bug 12675: Remove CGI::scrolling_list from labeledMARCdetail.pl

This patch removes only instance in this file.

Also updates getframework POD on C4/Koha.pm,
adds new GetFrameworksLoop() func on same file from
suggested code, but with ordered result.

To test:
1. Apply the patch
2. Enable viewLabeledMARC syspref
3. On staff, search for a record, goto detail view
4. Clic on Labeled MARC
5. Framework pulldown was replaced, check changing
framework.

A bug was fixed, because selecting any fw and then Default
tries to load values from 'Default' fw code, which does not
exists.
