ci(deployment): Skip deployment step on fork builds (#118)

The Travis CI build step for PRs originating from forks are currently unable to pass because they
don't have access to secure environment variables, causing the deployment step to fail. Deployment
of static previews for PRs is a useful part of our workflow, but not something that should prevent
contribution from those who don't currently have access to the main repo.
