Updated Edit Box Chat History

Updated Edit Box Chat History
-Extended the Edit Box History feature.  It will now store up to 40 previous history chat history lines.  This persists with each login on a per character basis.  This means if you logout and login again your history has been saved and loaded.  You can access it immediately by using the UP and DOWN arrow keys.
-You can now use the UP and DOWN arrow keys on the EditBox to go forward and back in the history without using the ALT key.
-Updated the order in which the history is saved and processed.
-Added a few error checks just in case the EditBox is not available on the first chat window.
