reorder help messages

[andyl]

Help messages are sorted in alphabetic order. That's a great default, and works most of the time.

But in some situations, I'd like to move a few lesser-used commands to the bottom of the list. Is this possible?

Yeah, seems like there could be an option to just show them in the order declared or something (which is what OptionParser does with ordering flags)
