Disabling WProofreader in source mode of WYSIWYG editors

Quite often we receive requests from our clients asking how to disable the proofreading option in the source mode of a rich text editor and keep it enabled only in the WYSIWYG mode. In general, for such cases, we offer a special option disableAutoSearchIn of WProofreader that allows disabling it for certain cases (class, id, data attribute name and HTML elements).
