/* 
Flash history management solution 
@notes:				swfName is a variable set via backend generated code 
@author:			Richard Leggett 
@updated 31/03/09:	Steve Smith		|	Decoupled HistoryManager, now relies on MooTools for browser detection. 
										Moved third party history keeper code into seperate file (library/js/thirdParty/historyKeeper.js)
@updated 19/07/11:  Edd Bignell     |   Updated HistoryKeeer to version 2.0B4 (library/js/thirdParty/unFocus-History-p.js) - now works with Chrome.
