Add attribute map support for .clone()

[Licensed to Gil]

Most of the time when I use the .clone() function, I'm cloning an element with an ID, so I have to change the ID with .attr() straight away.

I'd love to see the new $("<div/>", {attrMap}) syntax applied to .clone() as well, so that I could do:

$("#id").clone({id: "newID"});

Patch with unit tests here:

Feature creep...marking for review. To me the explicit .clone().attr() is better.

Agreed, explicit .clone().attr() is likely fine in this case.
