Fixed. The peak finder is created once, never destroyed. Window is opened and
closed as needed.

Fixed. "PeakFind" menu item is added once in the viewer constructor.

I am looking into it.

In the mean time, I copied&kludged code from TGFrame.cxx to make the popup menu pop
at the pointer position.

Also if histogram is plotted from context menu, the "plot in" menu setting is left
unchanged.

The other problem is multiple selection of histograms. Looking into it.
