[ Resending it as it seems like it never reached the mailing list.  ]

To make loading org-mouse less annoying for all, I was thinking of
introducing minor-modes like in the attached patch.  If this approach is
acceptable, I will get to calling out the change in NEWS and updating
the manual if required.  We could also add a `add-hook' call to turn on
the minor-mode automatically to preserve the old behaviour if required.
WDYT?
