.undelegate() with no arguments unbinds all handlers from the parent element

[[email protected]…]

This used to work in 1.6. undelegate() has a zero-argument version that should just undelegate all handlers from the parent element. What this does now is undelegate all handlers AS WELL as all bound event handlers on the parent.

See the following jsFiddle for an example: ​http://jsfiddle.net/xWju3/

Clicking on the div should display "Parent Clicked", and clicking on the "Click Me" button should display "Child Clicked". If you then click on the "Undelegate Click" button, neither the "Click Me" button nor the parent div will register their clicks anymore.

Yep, we'll get a fix in for this.

Fix #12203. .undelegate() should not remove direcly bound events.
