Title: Improve wrapMap

In most cases end tags are unnecessary and their absence make jQuery.buildFragment even more consistent across browsers, when jQuery.clean takes incorrect HTML argument as a string.

For example – in this pull, specifically in this line, jQuery#html takes as argument incorrect HTML-string, in new browsers, area element will be created, but in oldIE, you will have only map element, btw, oldIE always return coords value, even if it is not defined.

Incorrect HTML-strings should not be passed to jQuery methods, but it's nice when jQuery can process them more consistently across browsers and it will shave off couple of bytes.
