[Freeciv-Dev] (PR#13260) show icons in tech help

["Hogne Håskjold" <haskjold@xxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13260 >

In the "Allows" section for a given tech under help it would be nice to 
add icons in addition to the text link.

* Unit gfx for units
* Building icon for buildings
* Tech category icons for techs (new)

Additionally it could be restructured to only say "Allows:" once on the 
top, and have the icon where each "allows" is printed now.
