Added Travis Ci Testing

Hi, my proposed changes include adding Travis Ci build functionality by adding the appropriate Travis build test files. Travis Ci is a hosted continuous integration service that is integrated with Github. You can use Travis Ci to test against different languages. I set it to test the Javascript in this project to make sure it validates. What's great about Travis Ci is that with every future pull request, it will automatically test pull request code to make sure that it validates too.

In order to enable successful validation for the Travis build, I omitted the unnecessary semicolon at the end of each Javascript file.
