Add smart callback hook for monitor changed.
Add functions to return randr widget changed state. Add function to randr widget so we can apply changes. Add single randr_changed_set function (reduce duplicated code). Use E_INSIDE to determine cloning. Remove some printfs. Call randr_changed_set where needed. Signed-off-by: Christopher Michael <cp.michael@samsung.com> SVN revision: 81105
