bug #4652:
The content of a wysiwyg is indexed and rattached to its container (publication, form, etc...) except for webpages where wysiwyg pages exist by themselves.
Cleaning the code around UploadedFile to pass the uploader as a file attriute instead of a method parameter.
The WysiwygController can now create wysiwyg content that are NOT indexed thus enabling the update of the index of the container of wysiwyg.
