Bug 1487: Store the "display only used tags/subf" value in a cookie

Bug 1487: Store the "display only used tags/subf" value in a cookie

On the marc framework page, the checkbox to display only used
tags/subfields is always unchecked.
It should be stored into a cookie to always display the same view.

Test plan:
1/ Go on the marc framework page
2/ Check the checkbox
3/ Go somewhere else on the staff interface
4/ Back to the marc framework page, the checkbox should be checked
