    CI: add travis continuous integration
    
    Build and test GJS using Travis CI build servers. The goal is to automatically run the tests with every 
commit or pull request, implementing a continuous processes of quality assessment and control.
    
    Although the usage of dockerfiles and saved images is a better solution, it'll probably impact the 
maintainer experience by making it harder, or, at least, demanding new knowledge. Therefore, in order to 
avoid nuisance, as a first choice, I think it is better to keep the proposed solution as simple as possible: 
caches, scripts and no new assignments or learning process.
