First draft of pg_group admin tool.

I have a small tool I have written to do admin work on pg_group. With it
I hope we will be able to do most group admin without going into psql.
Like I said, it is a first draft, so it may have a bug or two :-)

It has the following syntax:

usage: pg_group options -- dB group [user ...] || [table ...]
where options is one of:
-c create group
-d delete group
-a add user(s) to group
-r remove user(s) to group
+g give group access to tables
-g revoke group access to tables
-p privlages to grant/revoke. This is only used with the +g and -g
options.
-- end of switches.

examples:
pg_group -c -- guestbook grp_gstbook_usr nobody tux
pg_group -a -- guestbook grp_gstbook_usr webuser
pg_group -d -- guestbook grp_gstbook_usr
pg_group -r -- guestbook grp_gstbook_usr nobody
pg_group +g -p "insert,select" -- guestbook grp_gstbook_usr gstbook
pg_group -g -p "insert" -- guestbook grp_gstbook_usr gstbook
