Title: Convert some methods of class Ponysay to class methods.

This converts all methods which are never called on an instance of class `Ponysay` to class methods. These methods did not have a `self` parameter and could only be called on the class object itself.

Also, this converts all access from these methods to the class object to access through the `cls` parameter, just to follow best practice.
