Adding .travis.yml

[Lucas-C]

The only things that remain are:

• activate your repo on http://travis-ci.org
• find a way to publish the binaries generated in dist/,
  for example using Github pages (I can help with that too if you want)

Build status & log of my fork: https://travis-ci.org/Lucas-C/scarr

Very cool! Thanks for doing this.

Getting the dist builds up on scarr.io should be as easy as putting S3 credentials in an env variable in travisci and using the s3 cli tool to publish them. I'll mess around with that in a bit.
