Add support for ark cookbook for installs.
Update project to use test-kitchen and serverspec.

This update bumps the version of test-kitchen and kitchen-vagrant
gems. There's a little bit of reconfiguring since the latest version of
test-kitchen uses the appropriate Opscode base boxes.

Additionally a few tests to test that the libraries are appropriately
dropped in the right directory and symlinked as such.
Add LICENSE file with Apache 2.0 terms.
Add checksum to the download package.
Update test-kitchen to make tests green!

Also adds more tests, more operating systems, and more cow bell!
Bump version of cookbook and use ZMQ 4.0.4.

This uses the latest stable version and bumps version to reflect.
