[PATCH] gitk: Add a visual tag for remote refs

[Josef Weidendorfer <Josef.Weidendorfer@gmx.de>]

This patch partly changes the background color for remote refs.
It makes it easy to quickly distinguish remote refs from local
developer branches.

I ignore remote HEADs, as these really should be drawn as
aliases to other heads. But there is no simple way to
detect that HEADs really are aliases for other refs via
"git-ls-remote".

To see the effect of this patch, you need remote refs in your
repository. Such refs are created when using "--use-separate-remote"
with git-clone.

IMHO showing HEAD refs as aliases to real refs would be nice to
have in gitk (What is the current branch?). Unfortunately,
"git-ls-remote", which is used in gitk, does not give the info
whether a ref is a symbolic link to another.
So for this time, I ignore remote HEADs, too. They are only confusing
as they would have been drawn now.

Josef
