AutoFieldWidget gets new useWriteStore option

If the useWriteStore attribute is set to true, the underlying data store
for dynamically create data will live in an ItemFileWriteStore instead
of a ReadStore, which allows the caller to modify the data after the
widget is rendered.  It's useful for in-place additions of newly created
items.
