Prevent overwriting jQuery and other common scripts

Browse source 
- Block third-party programs trying to load their own version of jQuery
- Block obsolete scripts such as xe.css and xe.js
- Block minified versions of the above, too
- Increase blocking index threshold from 1,500,000 to 1,500,000,000
- Add unit tests for script blocking
