--help and --version should still work

[reported by blelbach] [Trac time Fri Feb 24 04:04:31 2012] Even with the new namespaced command line options, we absolutely must have --help and --version. The following command line options should work out of the box:

Prints HPX version info:

hpx_application --version
hpx_application -v

Prints HPX command line help:

hpx_application --help
hpx_application -h

hpx_application -h hpx_application -v
Those work out of the box. DO we really need --help/--version as well?
