Continuous Integration: Migrate to Travis from Cloudbees

[kwin]

Travis https://travis-ci.org/ is easier to integrate nowadays and is never deprovisioned.

I had one small travis script working which builds the cppcheclipse, I was struggling to get the publish/deploy a realese working. But worked well for the build, so it is still useful to see if the project builds or not. Should I make you PR request for the .travis.yml as well?

[kwin]

Yes, please.

This could be done with this commit:

Travis build is now working in the background. Still need to include the according images in the readme to expose the latest build status (https://docs.travis-ci.com/user/status-images/).

[AntonKrug]

This should do?
