Problem: Deploying release artifacts is a manual process Solution: Use travis to deploy these artifacts automatically.

The deployment is triggered by tagging on the zeromq/libzmq repository.
Of the many builds travis is checking only the default one with
libsodium and drafts disabled is used for deployment.

For now the results of `make distcheck` are deployed as well as their
md5 and sha1 hash sums. Further changes may upload a generated
Changelog as well.
