Field Collection AJAX

The Field Collection AJAX widget is an alternative entry widget for field collections.

Instead of having every field collection entity directly editable, they are viewed in a table. There are AJAX-enabled buttons to edit each one, and a button to add another one; they are all edited in the same area beneath the table.

The table becomes much more readable, and managing multiple field collections attached to an entity becomes more maintainable.
