Incorrect function return type for jQuery setter functions

[RaymondLim]

jQuery has overloaded functions; both setters and getters have the same name, but setters have some extra parameters and most of them return jQuery object for chaining.

1. In a js file type $("div").css("display", "none").
2. Type a dot to chain the call with other jQuery api.

Result: You get hints for string methods instead of jQuery methods.

Reviewed. Marking medium priority to @eztierney for sprint 25 since it seems like a common case.

I looked through the jQuery docs, and I found 3 methods like this:
attr
css
prop

I didn't see any other methods which looked like they were overloaded like this, but I may have missed some.

three more -- height, width and html.

[njx]

A few more: offset(), text(), scrollLeft(), scrollTop(), .val(). (I found these by searching for "or set" on http://api.jquery.com/. There might be others, but these seem like the most common.)

Erik logged a Tern bug, see the comments in ternjs/tern#123.
