[albatross-users] [patch] to run from the command line

[Gregory Bond]

It'd be nice to be able to run cgi albatross programs from the command line to
check things like "is this a compilable python file".  Much easier to check
these things from the command line that fossicking though web error logs!
Currently, if you try to run an albatross CGI from the command line, it errors
inside albatross trying to get REQUEST_URI from the environment.

This patch make the program at least run and produce useful output when run 
from the command line without a REQUEST_URI set.
