Add autostow.sh ignore pattern to underscore dirs

Browse source 
autostow.sh will automatically ignore any directories it finds that
begin with an underscore. This will make it possible to remove the
default entires of AUTOSTOW_IGNORED_DIRS variable and thus remove some
of the magic and make autostow.sh behavior more predictable.
