[MuranoPL] MuranoMethodArgument does not reflect its "Usage" attribute

[Alexander Tivelkov]

There is no way to use reflection to check for the value of "Usage" attribute of Method Argument. Since the Standard and VarArgs/KwArgs arguments are quie different it may be useful to be able to detect their usage type using reflection.

    Event Notification pattern implemented

    This patch adds an 'Event' class which may be used to issue various
    notifications to other MuranoPl classes in an Event-driven manner.

    Any object which is going to emit the notifications should declare the
    instances of this new class as its public Runtime properties. The
    objects going to subscribe for the notifications should pass
    themselves into the 'subscribe' method of the Event along with the
    names of their methods which will be used to handle the notification.

    The specified handler methods must be present in the subscriber class
    (if the method name is missing it will be defaulted to the
    'handle%Eventname%') and has at least one standard (i.e. non-vararg
    or kwarg) argument.

    The class going to emit the notification should call the 'notify'
    method of the event and pass itself as the first argument. All the
    optional parameters of the event may be passed as varargs/kwargs of
    the 'notify' call and will be passed all the way to the handler
    methods.

    Since this approach relies on the reflection this patch also fixes a
    bug #1596647 since its fix is required for the argument reflection to
    work properly. It also documents new reflection capabilities which
    were added as part of the bugfix.
