title: Travis CI build when repository is first added
body: <p>Is it possible to trigger a build when a forked repository is first added to Travis CI? I just forked it and want to test the build before I start modifying the code. I know I can restart an existing build as described <a href="https://stackoverflow.com/questions/17606874/trigger-a-travis-ci-rebuild-without-pushing-a-commit">here</a>, but when a repository is first added there are no builds to restart. I also looked in Settings but could not find anything that would let me trigger a build.</p>
  
  <p>Edit: I also tried going to my GitHub repo -> Settings -> WebHooks &amp; Services -> Travis CI
  When I clicked "Test Service" I received the following error: "Oops, we weren't able to send the test payload: no pushes found."</p>
