NEWT Add: add<type>Listener(int index, <type>Listener l) ; get<type>Listener(int index) ; NEWTEvent attachments

NEWT Add:
    add<type>Listener(int index, <type>Listener l) ;
    get<type>Listener(int index) ;

    NEWTEvent attachments for listener to listener communication
    via object passing. This methodology is similar to the 'Atom'
    attachment of native systems.
    It is preferred to a 'consume()/isConsumed()' pattern,
    since it is less flexible and would 'endanger' system events.

TODO: <type>Listener[] get<type>Listeners() doesn't work and was always buggy.
