Travis integration

With checkstyle addon this provide great power!
We can test every pull request and every commit for ability to compile and codestyle. 
You can see a sample result just below from left of commit id.
Or direct by this [link][1].

After merge you should activate travis integration at travis-ci.org and activate hook in repository settings.
