reverting jqplot minification script

using find results in a different file order depending on the system. in some cases, this leads to dependency errors. therefore, we need to make the order of the files explicit.

libs/jqplot/build_minified_script.sh

 # build jqplot-custom.min.js
 # the yuicompressor needs to be set up in piwik/js (see piwik/js/README.md)
