 The KexiDataAwareView is used to implement differently-looking views 
 for displaying record-based data in a consistent way:
 - tabular data views
 - form data view

 Action implementations like data editing and deleting are shared for different
 view types to keep even better consistency.
 The view also implements KexiSearchAndReplaceViewInterface to support search/replace features
 used by shared KexiFindDialog.
