comparediffs, a tool to download, scrub, and compare PDFs

[kim-em]

I've written a script tests/diff/comparediff which automates downloading PDFs from two different sources, and verifying that pdfparanoia makes the files byte-for-byte identical.

There's a README, as well as a sample list of URLs to run on, which includes lots of examples where pdfparanoia currently fails.

Thank you.
