please attach binaries to release

[alehatsman]

Hello, thank you for the lib, if u could attach a binary to each release, that would be cool. Because that mean that i can easily provision my machines, just downloading binary i need.

Hope that makes sense.

Thank you!

Hi, I've now got a script that creates a .tar.gz with binaries for all platforms/architectures (using gox), as well as an associated CHECKSUM.txt file. These will be published with each release to https://github.com/shoenig/marathonctl/releases

Let me know if there's anything else I can do!
