Title: Improved filter performance on simple attribute selectors

I have a listener on the body filtered by a data attribute to create advanced tooltips. I use this patch to fix the performance problem (https://github.com/ArcBees/gwtquery/issues/177). I think that this simple filters on attributes are quite common for delegated event listeners, and this simple solves the performance problem in this situation.
