Finished some work from the weekend to keep local tree clean..

* Added a generic 'histogram' ui control, currently available in new image editor 
'scopes' region (shortcut P). Shows the histogram of the currently viewed image.

It's a baby step in unifying the functionality and code from the sequence editor, 
so eventually we can migrate the sequence preview to the image editor too, 
like compositor.

Still a couple of rough edges to tweak, regarding when it updates. Also would 
be very nice to have this region as a partially transparent overlapping region...
