Migrate to jQuery 1.10.2 from 1.10.1.

Include the minified version of jQuery 1.10.2 instead of 1.10.1. The 1.10.2
files were download via these commands:

$ wget -N http://code.jquery.com/jquery-1.10.2.min.js
$ wget -N http://code.jquery.com/jquery-1.10.2.min.map

Meanwhile, since the Javascript code is covered by GPLv3, we should always
provide an up-to-date version of the source code. I have included it
here by creating the directory jquery-src. I extracted the correct version
of the source with the following commands:

$ git clone git://github.com/jquery/jquery.git
$ git checkout 1.10.2

which is what the jQuery website instructs to do: http://jquery.com/download/

This repository is mirrorred at https://kallithea-scm.org/repos/mirror/jquery/ .
