Update CI and meta informations

[rafamanzo]

For all active Mezuro projects, we have to check the following:

• CI script
  • Minimal setup steps: we may have added some workarounds no longer necessary
  • Correctness
    • unit tests should run without any other services up to ensure proper mocking
    • Coverage check below 100% should fail the build
  • Improvements: take advantage of new features such as caching and container structure
  • Build against old rubies
    • 2.0.0-p598
    • 2.1.5
  • Make sure unit tests are run with no other services up
  • Fail build if the unit test coverage is below 100%
• META informations:
  • Complete README
    • Badges
      • Codeclimate
      • Build status
      • Coverage report
      • Waffle
    • Contributing: points to the most up to date description (becomes the CONTRIBUTING.md file)
    • Development: check for updates on dependencies and instructions (becomes the HACKING.md file)
      • See if curl is needed
    • Install(ation instructions)
    • License: header for the given one
    • Authors: points to the relevant file
    • Acknowledgements
  • Updated AUTHORS
  • Check COPYING / COPYING.LESSER presence
  • Check CHANGELOG presence
    • http://semver.org/ link to make explicit how to read the versions
  • Github repository description short and meaningful. Site points to mezuro.github.io.

Repositories to check:

• likeno
• kalibro_client
• prezento
• kalibro_configurations
• kolekti
• kolekti_analizo
• kolekti_cc_phpmd
• kolekti_metricfu

Kalibro Client's changelog is done, as well as a Travis update, but it`s still missing the coverage check.
