	* When a plugin is deactivated, the action 'deactivate_PLUGINNAME' hook is
	* deactivated. In the name of this hook, PLUGINNAME is replaced with the name of
	* the plugin, including the optional subdirectory. For example, when the plugin
	* is located in <tt>wp-content/plugin/sampleplugin/sample.php</tt>, then the
	* name of this hook will become 'activate_sampleplugin/sample.php'.
	* When the plugin consists of only one file and is (as by default) located at
	* <tt>wp-content/plugin/sample.php</tt> the name of this hook will be
	* 'activate_sample.php'.
	* @param string $file The filename of the plugin including the path.
	* @param string $function the function hooked to the 'activate_PLUGIN' action.
