title: Nightly build for release branch if branch exists
body: <p>I'd like to set up a nightly build for my release branch. Since I'm using git-flow I don't always have a relase branch so I would like it to build it if it can find a branch with a pattern of:</p>
  
  <p><code>refs/heads/release-*</code></p>
  
  <p>Any idea of how to get teamcity to perform this action for me?</p>
