Title: Added two jquery files to allow debugging of the jquery minified file

This is for issue #716. I will include some explanation and let you decide if we want to merge this or not. The error mentioned in #716 happens only in Chrome DevTools, actual users aren't being hit by this, and I also didn't see the error in Firefox/Firebug.

What happens is the minified version of the jQuery file contains a source map. This means if you have the unminified version of the file and the map file in the directory, you will be able to debug the unminified file instead of the minified one (in DevTools at least).

It boils down to do you want to have a 404 in some debug tool and debug the minified version, or rather not having those two files but being stuck with debugging the minified version (I don't know how often debugging JS code leads into the jQuery file).
