Comments with images

[gfr]

I added a function to EZComments so that a user can also add an image to a comment.

Please could you open a PR with this?

Is this really the right way? Should not we use a hook for that?

[nmpetkov]

One way to add images to comments, is to hook Scribite (visual editor) to EZcomments, with possibility to upload images (for example CKEditor with KCFinder).

Note: In this case, instead to show comment form under the commented content (with visual editor loaded), it is good idea to display a button only for adding comment. It is not implemented yet in the module, but is not difficult to implement.
