0 A.D. uses the demonym “Nuba”, which should be “Noba”, as pointed out by @Sundiata. This patch thus renames the Nuba village to Noba camp, and fixes all occurrences in the simulation and maps folders. While at it, also renames the “clubman” to a “maceman”, since its weapon is clearly a mace.
Art files could be renamed in a future patch (too many and too complicated for including here and now).

Check for completeness and correctness.
