rename QtHandles namespace to octave
To simplify the codebase, replace QtHandles top-level namespace by
octave. Since the header files for the Qt graphics code are not
installed, this change shouldn't cause trouble for any external
packages so we shouldn't need to provide an alias, even temporarily.

ButtonControl.h, ButtonGroup.cc, ButtonGroup.h, Canvas.cc, Canvas.h,
