cvsweb patch for ro annotate

[Gary Granger]

Here is a patch to cvsweb.cgi version 1.93 from Henner Zeller's cvsweb
download site (http://stud.fh-heilbronn.de/~zeller/cgi/cvsweb.cgi/).  I
found a simple change to allow annotate to work without write access to the
history file or repository directories: add the -n option with the
Global_option c/s message.  I can't remember seeing anything about this
recently, so hopefully this is useful and not redundant.
