Allow drop down display for individual field items

This feature request is dependent on this issue being completed first: #549920: Limit "Modify node fields" to specific fields

It would be really nice if the option below was available for each individual field:

Display operations as:

• Dropdown selectbox to choose which of the selected fields to edit
• Display all fields selected below for simultaneous editing of fields

This would be displayed under the "Modify node fields" container thus allowing you to choose from a dropdown one single field to edit rather than displaying all the editable fields at once as we see currently in the dev version. I feel that this would clean things up a bit when you are allowing several cck fields to be edited.
