title: Disable JSHint warnings in CodeMirror
body: <p>I thought this would be a trivial question, but I've done a ton of searching and haven't been able to find anything.</p>
  
  <p>I have a CodeMirror div that has linting turned on. I've included JSHint.js, which is working properly; syntax errors and warnings are being displayed in my CodeMirror editor. However, I need to disable a few warnings (most importantly, I want to allow unquoted object keys). </p>
  
  <p>Where can I pass preferences or disable warnings to JSHint so that it only shows the issues that I actually care about?</p>
  
  <p>Or, alternatively, is there a alternative to JSHint that allows more configuration (and is usable with the CodeMirror linting framework)?</p>
