Parameters for the new icons?

[Cloyd]

Hi DT,

Maybe I missed the explanation somewhere for the new icon parameters. (I did'nt find much in the guide.)

-Can any keyboard symbol be used, or only "+"?
-Color 3 is green, but what are the other color codes?

Thanks,
Cloyd

P.S. If this patch contained nothing but the mousewheel zoom for the map and FMB, I would call it a success. Thanks for ending that decade-long annoyance.
