Title: Add script to contrib/ that verifies authenticity of binaries hosted on SourceForge

This script downloads the SHA256SUMS.asc file from SourceForge for a given release (version can be specified on the command line), which contains Gavin's signature of the hashes of the Bitcoin binaries. It verifies that the signature is valid, downloads the files specified in the signature file, and checks that the hashes of these files match with those signed by Gavin.
