title: How to report console.error with Sentry?
body: <p>I have application where some critical issues are reported with <code>console.error</code> but are not <code>thrown</code> so application might continue to run - possibly in crippled state.</p>
  
  <p>It's necessary to report also <code>console.error</code> issues, but Sentry (Raven) library send to server only thrown exceptions.</p>
  
  <p>Does someone knows how to solve this nicely ?</p>
  
  <p><em>(ideally without need to rewrite all <code>console.error</code> calls, cause also some vendor libraries might still write output just into console)</em></p>
