Reenabled update of the histogram while doing color corrections
(bug 490182):
* app/core/gimpviewable.[ch]: added new methods preview_freeze()
and preview_thaw().
* app/core/gimpimagemap.c
(gimp_image_map_new): freeze the drawable preview.
(gimp_image_map_dispose): thaw the drawable preview.
(gimp_image_map_do): update the drawable, not the image.
* app/tools/gimpimagemaptool.c (gimp_image_map_tool_response): no
need to invalidate the drawable preview any longer.
