Allow shorthand for toolbar config

The toolbar module will assume if it gets a string or element it is the
container. Ex:

var quill = new Quill('#editor', {
  modules: { toolbar: '#toolbar' }
}

Previously it had to be { toolbar: { container: '#toolbar' } }

Adding a wrapper attribute to a format will cause the tag to be wrapped
in another element.
