Merge remote-tracking branch 'raspberrypi/master'

[timrowledge]

Hopefully this is all going correctly; this is the first attempt at doing this. Call me if I'm breaking something!

Revised documentation for the Scratch GPIO Server, with several new illustrations and descriptions of the new commands available.

I don't know what's gone on here, @timrowledge, but it isn't obvious what this PR brings in. You seem to have pushed a fast-forward merge bringing in all the changes you were missing in your working copy. I can't see any obviously intended changes to the Scratch docs.

Can you make sure your copy is up-to-date, then apply a commit with your changes, then open another PR?

Thanks

I have no idea Ben. There should be a revised usage/scratch/gpio/readme.md and four new png files images. I noticed in my copy of 'SourceTree' that this morning it tells me the .md file wasn't 'staged' whatever that means. So I (re) committed it and a new pull request seems to have been created.
The four new png files are sitting ai list of 'staged files'. Let's see if I can do something with them...
err... that results in a webpage assuring me that five files are committed.
