title: How do you make grunt.js not crash on warnings by default?
body: <p>I'm using Grunt to compile CoffeeScript and Stylus with a watch task. I also have my editor (SublimeText) set to save files every time I page away from them (I hate losing work).</p>
  
  <p>Unfortunately, if Grunt hits a syntax error in any of the files it's compiling, it throws a warning and quits with <code>Aborted due to warnings</code>. I can stop it doing this by passing <code>--force</code>. Is there any way to make not aborting the default behavior (or control which tasks' warnings are important enough to quit Grunt?</p>
