more of: experimental patch to use stale group data if server down

[Aaron Nabil <nabil@spiritone.com>]

I reversed the "old" and "new" in the previous patch.  Here it is again
with more added, as it occurred to me that you could extend this idea 
a bit.  If you didn't know the server was down, but then it turned out 
it was, use the cached data if it looks valid.

Not tested much, experimental, standard disclaimers apply, etc...
