Create .travis.yml (#14)

* Tested with travis.ci and the result is good.
- I tested it by adding random strings into .py files in the repo(to generate the errors), and it triggers the errors.
- Second test, is by removing the random strings (or make the file as before), and the build is passing.
- Third test, added random string  into apps/files, and it generates the errors for the build. (as long PythonOS/pyos.py called the program or specific functions?)
- Fourth test, removed, and builds passing.
