[Freeciv-Dev] (PR#7440) don't hard-code standard and oil mines

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://rt.freeciv.org/Ticket/Display.html?id=7440 >

Currently oil mines are drawn on desert and arctic, while "regular" 
mines are drawn on hills and mountains.  This is hard-coded in tilespec.c.

With this simple patch, the sprite to use for a mine is put into the 
tileset terrain data.
