Codemirror - show syntax errors

[iliakan]

How can I enable showing syntax errors in CodeMirror? Like a normal editor.

CodeMirror has linter for this:

I'm not familiar with it, but here's an example of using it:

Do I need to patch tutorialkit, or there's a better solution?

In #213 we'll be adding support for showing syntax errors for Javascript.
