Add an extra boolean parameter that will return the value of the removed attribute, instead of the element. So "removeAttr('foo', true)" would instead return "bar" as opposed to the jQuery object to chain. Would be useful instead of needing to store the selected element in a variable, only to call it again as one cannot remove the attribute and return its value in one line.
The same notation can be used for the removeData and removeProp methods, also if there are more than one element it will only return the value of the first selected, to keep with standard seen in the attr, data and prop methods.
Would anyone else find this usefull? I almost always use it in any project.
