Feature request: include page number (if relevant) in automatic edit summary

[colinmorris]

In the case where an image is extracted from a multi-page document, it would be nice if the page number were mentioned in the edit summary. e.g.

File:Foobar.pdf page 17 cropped 22% horizontally, 37% vertically using CropTool with precise mode.

The use case here is that a reader looking at an extracted image might want to see it in context, and doing a linear search of the original document to find the page from which it was extracted can be time-consuming.

#74 contained the related suggestion of including the page number in the new filename. I'm a little less keen on that idea, since I often completely replace the suggested filename with a different name according to the purpose of the cropped image.
