Changelog: 
Version 1.5 
– Tested on WordPress 3.7.1
Version 1.4 
– Updated the jsPgnViewer javascript to the latest version (0.6.7).
Version 1.3 
– Fixed error that caused preview not to show up within the WordPress admin after changes were made.
Version 1.2 
– Compatibility with WPMU improved. Made changes to how code is inserted into posts. Instead of game it now defaults to ###pgn### game %%%pgn%%% because this is a bit more compatible, especially with WordPress MU. The tags will still work, though.
