------------------
* Display fields from behaviors in the schema preview too.
[davisagli]
* Prevent the user from creating fields with names that are reserved for
Dublin Core metadata. ``title`` and ``description`` can still be used
as long as the fields are of the correct type.
[davisagli]
* Remove unhelpful help text for min_length and max_length fields.
[davisagli]
* The schema listing preview now respects autoform hints (such as custom
widgets).
[davisagli]
* Make new boolean fields use the radio widget by default. The field now
appears as "Yes/No" in the list of field types.
[davisagli]
* Hide the 'read only' setting for fields.
[davisagli]
* Edit field defaults from the schema listing instead of in the field
overlays. This simplifies making sure that the default can't be set
to invalid values.
[davisagli]
* Limit the height of text areas in the schema listing to avoid extra
scrolling.
[davisagli]
* Fall back to normal traversal if a field isn't found when traversing the
schema context. This fixes inline validation for forms on the schema
context.
[davisagli]
* Make it possible to make the schemaeditor not be the default view of the
schema context, by specifying the ``schemaEditorView`` attribute on the
schema context.
[davisagli]
* Added Spanish translation.
