9826	Prevent including pluggable.php by plugins	lilyfan		"It is a bad manner to include wp-includes/pluggable.php by plugins.

Some plugins (such as [http://wordpress.org/extend/plugins/events-calendar/ Events Calendar]) DOES the implementation, and cause confliction with other plugins which overloads the functions in pluggable.php

To prevent this implementation, insert some code to check the valid timing to load pluggable.php.
