Adding capture to allow better event delegation

[justinbmeyer]

in event.js line 10

from

add: function(elem, types, handler, data) {

to

add: function(elem, types, handler, data, capture) {

AND line 73 from

elem.addEventListener(type, handle, false);

to

elem.addEventListener(type, handle, capture

false);

this is needed for blur / focus (which do not bubble) to work.

#5263 is a duplicate of this ticket.

Thanks Justin. Seems reasonable.

I don't think this is needed anymore.
