lib.App: Fully parse argparse tree if _ARGCOMPLETE

Browse source 
Every module derived from lib.Cmd implements its own
parser.add_argument() logic. As a consequence, all Cmd derived
modules need to be loaded to have the full argument tree available.
This is avoided during normal program startup because it takes some
time. It's not necessary during normal program execution, nor for
showing help messages. It is, however, needed for argcomplete to do
its thing, so fully parse the command line if the program runs in
argcomplete mode, as determined by checking if _ARGCOMPLETE is
present in the environment.
