Mason callback support via Params::CallbackRequest

MasonXInterpWithCallbacks subclasses HTMLMasonInterp in order to provide a Mason callback system built on ParamsCallbackRequest. Callbacks may be either code references provided to the C constructor, or methods defined in subclasses of ParamsCallback. Callbacks are triggered either for every request or by specially named keys in the Mason request arguments, and all callbacks are executed at the beginning of a request, just before Mason creates and executes the request component stack.

This module brings support for a sort of plugin architecture based on ParamsCallbackRequest to Mason. Mason then executes code before executing any components. This approach allows you to carry out logical processing of data submitted from a form, to affect the contents of the Mason request arguments and thus the ARGS hash in components, and even to redirect or abort the request before Mason handles it.
