CI status for libraries

Hello fellow @hoackers and users!

I am happy to announce that all libraries with test suites now have been configured on the CI, aka Travis, see RFC 36 for more details. There is a summary of all the status here,

Some build status are red because of network issues, or timeout issues. Test suites are failing only on Travis. But you can help!

Some code coverage scores are unknown because Coveralls. Maybe it will be fixed one day if another payload will be send to it.
