Make default chat nick colours like the mockup chat screenshots as discussed
The attached patch makes the Gajim defaults the same as the mockup pictures discussed. Here is a screenshot of my current gc window with these settings applied. http://arker.homelinux.org/~dcraven/chat-nick-colours.png
NOTE: Part of this patch is to add bold style to the inTag and outTag texttags. Since this is not a configuration option, if this patch is applied it may cause retina damage to those who are already using the currently default red and blue colours.
