TNG Plugin Remover

<?php
/*
Plugin Name: TNG Plugin Remover (tpr)
Plugin URI: http://www.hcnhistory.org.uk
Description:  Removes some plugins from TNG pages
Author: Peter Cooper and Kamil Grzegorczyk
Version: 1.0
Author URI: http://www.hcnhistory.org.uk

/*
 * This is based on Cart66 remover from http://lowgravity.pl/blog/quick-tip-how-to-disable-wp-plugin-on-certain-page/
 * (see also https://gist.github.com/markjaquith/1044546 for something similar and better comments)
 *
 * It is needed because TNG and some WordPress plugins (e.g. Tippy) can conflict (e.g. because of multiple jQuery loads)
 * It avoids the conflict by simply preventing listed plugins from being loaded on TNG pages.
 *
 * To adapt this code for your WordPress/TNG integration, TAILOR it where indicated and save in your wp-content\mu-plugins\ folder
 * mu means Must Use - plugins in here are run before everything else - see http://codex.wordpress.org/Must_Use_Plugins
