title: git username change not reflected in webstorm/teamcity
body: <p>I'm trying to get TeamCity, WebStorm, git and GitHub all communicating.  It's working, with the exception that all checkins show up with the username "scott.beeson".  When I checked my .gitconfig, the user name was "scott beeson".  Obviously, it replaced the space with a period, that's no big deal.  I am now attempting to make it match my GitHub username, which is completely different anyway.  I've modified the file as well as tried the following command:</p>
  
  <pre><code>git config --global user.name "githubUserName"
  </code></pre>
  
  <p>If I exit the command prompt and launch a new one, calling "git config --global user.name" does show the correct (new) username.  But when I do a commit and push from WebStorm, TeamCity still shows scott.beeson.</p>
  
  <p>I also tried reinitializing the repo from the command line.  Still didn't change anything.</p>
  
  <p>What am I missing?</p>
