Named Event Arguments

[tobias382]

If Phergie_Event_Request::getArgument() receives a non-numeric string, it should check for an internal associative equivalent of the existing enumerated arguments array. If one does not exist, it should be created. The associative indexes used and argument values with which they are associated will depend on the event type. Once the array exists, the argument value corresponding to the string value received by getArgument() should be returned if it exists.

call could return these values for corresponding method calls. Ex: For a JOIN event, getChannels() would return the first argument.
