[Freeciv-Dev] (PR#3003) Different colors in text/chat window

["Guest via RT" <rt@xxxxxxxxxxxxxx>]

Hi,

It would be nice if text from users (chatting) in the text box would be
colored differently. This way it would be easier to seperate these
messages from the normal game messages.

Perhaps all messages should be categorized and colored in a consistent
style (e.g. technology messages blue, city messages yellow, etc.) - but
the first issue is what bugs me the most :-)

Thanks.
