Returns a transformed hash in which all camelCased property names have been replaced by dashed property names. The
input hash remains untouched.

Property values are not modified.

Simple implementation, but good enough for the attribute names we deal with here.

Example: { fooBar: "whatEver" } => { "foo-bar": "whatEver" }

@param   {Object} hash
@returns {Object}
