Fixed issue https://github.com/codesake/codesake-dawn/issues/19

cocaine gem is reported to be vulnerable even with version 0.3.x.
CVE-2013-4457 is only for 0.4.x and 0.5.x where x=[0,1,2]
A new Roadmap to hit 1.0.0 very soon and postpone some aux check to a
1.2.0 release
Rename spec files, so rspec actually runs them.
