Group buffer highlighting

Group buffer highlighting

[Lars Magne Ingebrigtsen]

I've now done the code to highlight the group buffer, but I haven't
selected proper colors -- they are pretty random at the moment.

The `gnus-group-highlight' variable controls the fontification of the
group buffer.  Suggestions for a nicer value for that variable is very
welcome.

How 'bout trying to emulate the summary buffer color code?  That
should make it easier for the user to get an intuitive idea of what
they mean.  Let's see...

[ The same shades of the primary colors should be used as in the
summary. ]

red: group has ticked/dormant articles but zero unreads, and
     5 <= group level < 2

bold red: group has ticked/dormant articles but zero unreads, and
	group level <= 2

italic red:
	group has ticked/dormant articles but zero unreads, and
	group level < 5


blue: group has zero unread and zero ticked/dormant
       5 <= group level < 2

bold blue: group has zero unread and zero ticked/dormant
	    group level <= 2

italic blue: group has zero unread and zero ticked/dormant
	group level < 5

default: group has unread articles.
       5 <= group level < 2

bold default; group has unread articles.
	    group level <= 2

italic default: group has unread articles.
	group level < 5

green: zombie group.

yellow on black: killed group (perhaps too strong)

That's the closest I can get on duplicating the color encoding.  

nndoc, nndraft, nnvirtual, and nnkiboze should each get some noticable
color.
