Change CI provider

[esttorhe]

Given that TravisCI is pretty horrible and during #47 I was unable to grep or even read the failing logs…

Maybe it is time to re-consider a move of CI provider.
BuddyBuild or CircleCI are the ones that come to my mind but perhaps there are other that could be good to adopt.
