Title: Removing references to attrFn to support jQuery 1.8 core

This was an undocumented "internal" variable in jQuery core, and has been removed in 1.8.

It makes it so that if you call `attr( property )` with a property, it passes it to `$.fn[ property ]` - You probably don't want this for events anyway
