xF1 Add-on Defer JS 2.2.4

This add-on moves javascripts in page output to the bottom of the page. This has a noticeable impact on page-load times as pending HTTP requests postpone rendering of a page, while scripts aren't run until everything is loaded anyways.

There is a blacklist available in the options for scripts that don't play nicely with this add-on.

This add-on requires PHP 5.4+!
Trying to install it on earlier versions will break your forum.
