Log:
wlanstats: add help
- add a help (-h) flag
- move usage into itsown function
it looks like the only change now is that usage info always go to stdout,
and exit code differs. i don't think it should be mfced.
It also removes the double printing of the program name (correct) and the
printing of "usage: ", and has mounds of style bugs.
gnu utilities have a --help flag that causes similar behaviour (printing
to stdout and exiting with status 0), but they still print error messages
about usage to stderr.
