support for saving a modified image instead of original version

Normally when you save an image through the "Save..." entry in the
context menu for an image, the saved image is the original one more
eventually applied filters (which are not removeable).
Further applied transformations like rotation, cropping, color effects
are not included in the saved image.
This patch offers the user to choose if saving the original image
(with filters) or the modified version through a pop-up dialog.
The new feature is available in Writer, Draw and Calc.
