Build on Travis CI.

Always a good thing for a project to have a Travis CI chicklet. I'd like to be able to build on Travis CI before submitting a pull request.

If I were to implement this and submit a pull request, I'd be curious to know @jindw, do you work on Windows or UNIX? If you work on Windows, I'll boot Windows to make sure that you'll be able to do anything build related that I might change in some way.

hi

I usually work under the windows, I'll switch to my linux environment when npm publishing, because a bug in the nmp early.
I do not know Travis CI, but this sounds cool, I'm willing to try, thank you

@jindw One of two ways to proceed with Travis CI. Go to Travis CI, log in, list your repos and turn on xmldom. I'm all set to push to Travis CI to build.
