Changed explanation of the ‘cache’ setting for ‘ajax’ and ‘getScript’…

… to say it works, when set to ‘false’, by appending a counter value rather than a timestamp (see: jquery#1241).

You can also make a JSONP request, have it received as text, and interpreted by jQuery as XML: <code>"jsonp text xml"</code>.
