Title: pass class names to the <img> tag

The commit is about passing class names to the tag. An escenario is passing the `img-responsive` class when using Bootrstrap.

I changed `bind-attr` for `unbound`. I don't see why we would want to keep around un-used binds, please correct me if I'm missing a use case.
