[Freeciv-Dev] (PR#15644) Renaissance city style

["Daniel Markstedt" <himasaram@xxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=15644 >

A 'Renaissance' city style is listed in our default ruleset, but
graphics are defined as 'Industrial'. 

This patch makes it possible for future tilesets to make use of this.
