lamson.args cannot interpret True as bool

[wRAR]

If you use some -arg it will be set to True. You can also pass -arg True and it will be still set to True. But you cannot pass False in any way, you can only pass "False" which is pointless and misleading.

I've also found http://pydoc.net/lamson/0.9/lamson.args which says "if you give a boolean then your users can indicate that boolean is true by giving just the option (-horribly) or specify the truth (-horribly False)" which is even more misleading (maybe that's why it was removed in later versions).
