Add graphic size checker for the preferred document DPI

This change adds a graphic size checker, which checks all the
images in the document, if they largely differ (outside of 50% and
110% of the image size) from the set preferred image DPI document
setting. For all images that don't fall under this bounds, list
them in the dialog and offer the posibility to select/goto the
image and pop-up the properties dialog for the image to change
its size.
