+* supportsDirectEditing and supportsDirectApiEditing methods added to
+ContentHandler, to provide a way for ApiEditPage and EditPage to check
+if direct editing of content is allowed. These methods return false,
+by default for the ContentHandler base class and true for TextContentHandler
+and it's derivative classes (everything in core). For Content types that
