more useful connection status colors

[rootbeer23]

mahlzeit!

there is an opportunity to make the connection status colors more meaningful.
A player color could be different if the player is not connected to an observer or if the player is not
connected to somebody who has neither a player nor observer slot, probably because of a timeout or sth similar.
I.e. in lobby.lua:CalcConnectionStatus you could assign yellow to players who are not fully connected
to all players in player slots and a more greenish yellow to ppl who are not connected to an observer or a "ghost",
similar to how it is done in lobby.lua:EveryoneHasEstablishedConnections.
What would have to be done to change lobby.lua on my own computer, in case i wanted to take a shot at it?
Can i redefine the function without changing faforever.faf and if not, can i just unzip->edit->zip the file?

Also, a question... is there a way to determine that an error report in the bitbucket issue tracker is due to an application
crash in the ForgedAlliance.exe lobby and whether the bug reporter was host or not?
