Identify in the preview doesn't update the overview

[Bruno Postle]

Most operations in the preview, such as drag or crop, update the overview immediately. Similarly changes in the overview update the preview immediately.

If you enable 'Identify' and move the mouse around the preview canvas to highlight photos, then these photos are only highlighted in the preview and not in the overview. The reverse is also true, highlighting photos in the overview doesn't highlight them in the preview.

I've attached a patch to fix this bug. It essentially takes the guts out of PreviewIdentifyTool::ImagesUnderMouseChangedEvent() and puts it in another function called UpdateWithNewImageSet(). ImagesUnderMouseChangedEvent calls a new function in GLPreivewFrame which in turn calls UpdateWithNewImageSet on the three PreviewIdentifyTool objects it contains.

I've tested on Windows 7 64-bit (64-bit build), openSuse 11.2, and Mac OS X (10.6) and works well on each.
