title: Logging Codeception Errors
body: <p>I'm pretty new to Codeception and I have come across a problem I cannot figure out.  I have about 40 tests in my test suite, and if a test fails, I need to send an email with the reason it failed.  For example, if Codeception cannot find an element on the page resulting in a failed test, I need to send an email with just the error, like this:</p>
  
  <blockquote>
    <p>Failed to verify emailing wish list behaves as expected in ThisClass::thisTest (/home/qauser/codeception_tests///acceptance-mobile/Wishlist/EmailWishlistCest.php)
    Couldn't see "Success!","//*[@id="wish-list-confirm-popup"]/div/div/div[1]/h4":</p>
  </blockquote>
  
  <p>I don't want to send the full stack trace, just the actual error.  Does anyone know if this is possible?</p>
