Transmit playercolor changes on the network

[Mariculous]

I just backported the playercolor change over network transmission from extended.
Greetings to the pak192.comic team!

This was deliberately left out, so everyone could choose his own favorite color (which may be important if you are color blind). However, if there is demand for this why not.

Is this feature used often on the extended server?

Yes it is. On BB server each company has changed their color two or three times on average over 300 ingame years.
And I've heard from the pak192.comic community that they miss this feature pretty much in standard.

Thank, indeed pak192 uses much more player color. INcorporated in r9752

I think in simmenu.h the constant TOOL_RECOLOUR_TOOL should be added before SIMPLE_TOOL_COUNT

Indeed, r9754 fixes this

Thanks a lot for all of your work here!
