Emmet with CodeMirror

[zoltan-nz]

Adding Emmet in a project where we use ivy-codemirror is a quite simple solution. (https://github.com/zoltan-nz/tutorial-builder/blob/42c46955536d57dd3a195ea42a587bdc6e980cb2/app/components/ivy-codemirror.js)

However, I tried to create an Ember Addon to extend ivy-codemirror with that, unfortunately it's not working, because I have to extend IvyCodeMirror.

Probably it would be better, if this kind of extension would be an optional option in ivy-codemirror package.

What do you think?
