Addresses sudo dependency and dependency on "pi" user, to more gracefully handle multi-user environments. See #15.

Briefly:

[edit] Note: Users should run ScratchGPIOPlus versions when working with addon boards. The basic version sets 11,12,13,15,16,18 as outputs and most of the other pins as inputs (with pull-ups) - this is useful if jsut using breadboards (as we did in the initial days) The plus version doesn't default any pins to any state and is the one to be used when using addon boards.

On pedagogical grounds - I don't think including a full working example of a Pibrella on launch of the program is a good idea - it sort of defeats the point of learning how to do something :)

Ah, I didn't know about the pullups. I didn't notice any problems with the Pibrella without them. I can reinstate the commented-out blocks.

I discussed this with the class leader. He took the view that having the Pibrella test sample launching on default was useful as it allows the supervisors to easily check the Pibrella's functioning prior to letting the students loose, and he showed me that dragging the code blocks to the left would delete them. Perhaps this is something that I should do locally in post-install, as I can see that it would be counter-productive in other cases.

The first Pibrella session this morning "all went perfectly" according to the class leader. Thank you so much for your help.
