New version of gitk

I have just put a new version of gitk at:

	http://ozlabs.org/~paulus/gitk-0.9

I'm pretty happy with the display side of it now.  When you select a
commit it displays the full diff below the commit comments in the
bottom-left pane, with the diff displayed nicely with red and green
backgrounds for the removed and added lines.  There is still plenty to
do in the areas of user preferences, menus, find facility, etc.
