Subject: [PATCH] Precursor change to akkana and hyatts fix for platform
 dependent key-bindings.  HOME and END will now implement the scroll to top
 and scroll to bottom for mac.  Scroll and Move for pageup/pagedown and
 CTRL-HOME and CTRL-END on windows will not work until m13.  This is ok for
 now and will hurry up completion of M12. r=akkana.  simple fix like 10 lines
 really.
