Prototype's Event system need to be fixed

[buda]

1)
Since IE9 IE has addEventListener - so it has to listen events in
standart W3C way -> so it has capture events
I use capturing very often - so I forced, instead using on or observe,
use addEventListener

2)
In the library's code there are planty tones of check - 'if
(element.addEventListener)'
I believe that they could be replaced by somthing like this:

if (element.addEventListener)
eventListenerFn = 'addEventListener'
else
eventListenerFn = 'attachEvent'

and than everywhere use - element[eventListenerFn] or somthing else

I've seen on github that event system is reworked, but this is still work in progress. You can download bleeding-edge version and test for yourself.
