Now the dialogs use a copy of the ramp, and the edited ramp is retrieved by calling ramp() on the dialog after it is executed. Avoids pointer lifetime issues by storing and working on a ramp pointer which the dialog does not have ownership on. Also fix a bunch of leaks relating to cloning color ramps.
