Title: Improved doc to specify required options when using polymorphic form

When using the `polymorphic` `belongs_to` form of associations, it is required that the `acts_as_superclass` method is passed `as:` option specifying the name of the association. Without this features like `superclass.specific` does not work. README must reflect this, as it does for `acts_as` method.
