Subject: [PATCH] feat(jqLite): add triggerHandler()

we need triggerHandler() to become jQuery 1.8.x compatible.

this is not fully featured triggerHandler() implementation - it doesn't
bother creating new DOM events and passing them into the event handlers.

this is intentional, we don't need access to the native DOM event for our
own purposes and creating these event objects is really tricky.
