[PD] pduino rewrite

[Ingo]

I did test it with the Duemilanove. But I also tested Diecimila and Uno.
To me the problem looks like "unfortunate design" in the firmata. The
buttons 2-9 don't somehow connect the same 8-bit word. It might simply be a
bug in the firmata. Hans hasn't reacted to it the last 2 or 3 times I
mentioned it.

I have changed my arduino patch to get it to work for what I need with the
Diecimila to Uno. I don't like to submit any workarounds if I don't have a
mega available. I don't know how the rest of the pins are set up in blocks.
It might also break something else since I only use part of the functions.

I really think Hans is the one who should look into this problem to
determine whether it is a pduino or firmata bug.

I am really surprised that so few people have problems with this. Or maybe
they do and simply cannot figure out where the problem comes from?
