[Freeciv-Dev] (PR#13588) images for techtree

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13588 >

The techtree images should be optional.  It should be easy to 
enable/disable them with a flip of a checkbox right in the dialog.

The reason is for experienced players (i.e., me) the techtree is a 
faster way to set your tech goal and current research (compared to 
drop-down menus).  But pictures get in the way by making it 
unnecessarily much larger (in particular, it makes it scroll in both 
directions).

I realize this may not be too easy.
