Texteditor.AutoClip -- enable/disable auto clipboard copy
When the gadget is in read only mode and the user marks some text,
then it will be automatically copied to the clipboard. With this
tag you can disable that behaviour, but think twice, because the
configured 'copy' key (which the user normally uses to copy text)
will only function when the gadget is active (or default) which
it won't automatically become in read only mode (when clicked).
