start argparse conversion; not working yet (main issue is parse_args now returns args instead of (opts,args))
argparse upgrade
more work on config files
config files now work with all queue types; add config files and .gitignore
update config file handling and option parsing; remove some hard-coded defaults and add new options which can be supplied via command line flags, env, or config file.
mostly fix some walltime-related stuff
update INSTALL/README/setup
Merge pull request #154 from bcdarwin/configargparse
