0.6.0

This new version (released March 1st, 2016) is mostly a "code quality" version, with small feature added to extends the plugin and to handle a new Adyen HPP field.

Also, there is a documentation now!

• Allow plugin user to extend it with get_class,
• Split several methods in order to override specific parts of the plugin,
• Expose more methods as public methods to allow plugin user to override more specific parts of the plugin,
• Add deprecation note on handle_payment_feedback and add two separates methods to handle payment return case and payment notification case.
• Add allowedMethods to the payment request form (unused by default).
• Start a sphinx documentation for the project.

This version is backward compatible with version 0.5.0.

Note that plugin users need to implement method get_allowed_methods if they uses their own config class from the abstract config class.
