fix addEventLister detection for IE9
fix addEventLister detection for IE9

IE9 added support for addEventListener and it looks like some
new events (e.g. DOMContentLoaded) can't be registered via attachEvent,
only addEventListener correctly registeres these. So to make sure
we are using the latest and greatest we need to look for addEventListener
instead of attachEvent in the jqLite feature detection code.
