Playground getting reorganized, comments please

It was more of a organizational thing than anything else, to be honest. Not trying to start a war or spend too much time on it. I just thought that people looking for information on their Arduino (on the Arduino website) might be more interested in ways to power their board or burn the bootloader than in arguments about trademarks. They feel conceptually distinct to me: one is more of a "how to" and the other (the hardware, not the trademark disputes) is more of a "related resources". Plus, we had two lists of third-party hardware on the page, and it seemed to make sense to consolidate them. Also, the lists of text without links didn't seem particularly useful. Again, not trying to start a war here, just find a organization that makes sense for the people using the site.
