Title: fixed showing no 'Usage'.

mruby command not shows 'Usage: [swiches] programfile' with no switches or wrong switches.

Not Fixed
$ mruby /* no switches */
$ mruby -h /* wrong switches */

Fixed
$ mruby
or
$ mruby -h
Usage: mruby [switches] programfile

-b load and execute RiteBinary (mrb) file
-c check syntax only
-e 'command' one line of script
-v print version number, then run in verbose mode
--verbose run in verbose mode
--version print the version
