[Freeciv-Dev] RFC: citizens and citizen sprites

[Jason Short <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

Currently the client's system for accessing citizen sprites is very
hard-coded.  It is not easily extensible.

IMO it is very bad that male and female sprites are hard-coded for
workers and disallowed for specialists.  Therefore my proposal is that
these two concepts be separated.

* enum citizen_type be created to hold the 7 different citizen types.
* For each citizen type there may be up to MAX_NUM_CITIZEN_GRAPHICS
sprites.

This combination allows a lot of cleanup as well as introducing some new
graphical abilities.  The cleanup makes Rafal's idea for
city-style-based citizen graphics simpler.

I'll supply a patch, but it depends on (=conflicts with) PR#2490.
