Links to pdfs aren't working (docs/PDF/PDF.md)

[dylanmc]

For example, the first (download) link goes to
http://corkami.googlecode.com/svn-history/r480/trunk/misc/pdf/encode-hex.pdf
Which doesn't work now.

I was also surprised the example PDFs weren't in the repository.

ah, thanks - the examples are likely in https://github.com/corkami/pocs/
