Experimenting with using Travis CI for a Racket project.

Until Travis CI gets built-in support for Racket, we can use the before_install clause of .travis.yml to download and run the Racket installer.

To add this capability to your project, simply add the example .travis.yml to your repo. You may need to change its script section's raco make and raco test parts.

NOTE: In the before_install: step, be sure to pipe the install-racket.sh script to bash (not to sh).
