Allow comments on the rules method of the Request class

[Ken-vdE]

I've expanded the functionality to allow comments and hidden params to also be defined within the PHPDocs of the rules method in the Request classes.

@lrd comments defined on the controller methods are appended below the @lrd comments defined on the Request method.

@LRDparam defined on the Request method are combined with @LRDparam defined on the controller methods. However, when a param with the same name is defined on both, the controllers definition will take precedence.

P.s. There is an error in your readme.
An example is given to determine response codes:
@LRDparam responses 200,422
However, that should be @LRDresponses 201|244
