New Board for Raspberry Pi discussions and information

[Jason]

At the suggestion of Fox, I created a new board specifically for the Raspberry Pi and other similar single-board computers. Note if you need support for the Pi or other such devices, you should start a new topic on the Support board. I probably messed this part up but if you see a deal for a Raspberry Pi or have one to sell, you should post that in Marketplace. Anything else can go here.

I've moved every post I could find concerning the Pi into that group so we'd have lots of content there to start off. I was surprised at how many posts we've had related to the Pi over the years. The list of topics fills two pages! Hopefully, there will be lots more to come.
