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

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.
