title: Trigger a build in TeamCity whenever a tag is present in the commit
body: <p>I am using TeamCity 9.01 as my CI server. I am currently using a VCS trigger which will trigger for a regular expression. But this regular expression in the commit message is making the look of work flow in source tree a little too clumsy. So I decided to trigger a build whenever a tag is added. But I couldn't find any solution.Please help me out.</p>
