-Added code to detect a Barns and Noble Nook and apply key bindings for next/previous page for the 4 front left/right buttons.
-Modified to load the Nook key bindings from a Nook specific file.
-isNookTouch() method will return true only for a Nook with no volume keys who needs the keymap-nook.xml key bindings. A Nook Color and Nook HD will use the default FBReader key bindings.
