Implement "cdata" property for pushbuttons (bug #44332).

* ToggleButtonControl.h (update): Add protected function to class.

* ToggleButtonControl.cc (ToggleButtonControl): In constructor,
create a QImage from "cdata" property and apply it using setIcon().
* ToggleButtonControl.cc (update): New function to handle changes to
object properties.  Decode "ID_CDATA" in switch statement.  Create a QImage
from "cdata" property and apply it using setIcon().

* PushButtonControl.cc (PushButtonControl): In constructor,
create a QImage from "cdata" property and apply it using setIcon().
* PushButtonControl.cc (update): Decode "ID_CDATA" in switch statement.  Create
a QImage from "cdata" property and apply it using setIcon().
