Lab 5 Docs - confusion and body.json step

[eric-wayne]

Feedback on the documentation for Lab 5.

1. The https://github.com/watson-intu/self-sdk/tree/develop/docs/workshops-devcon/5/lab-docs directory contains two PDF files and an md file. It's a bit confusing which one to follow in what order.
2. Specific issue: As I followed the Raspberry_Pi_IntuSetUp.pdf instructions, when I came to step 4.a.2 under "Retrieve the latest self-sdk and build Self on your Raspberry Pi", I received an error since body.json did not yet exist in that location. I first needed to run the build on the Raspberry pi and then only after that was a body.json file present.

I've followed the instructions in this repo's README.md for Raspi, and I'm encountering a compile issue while building target sensor_plugin, ExampleSensor.cpp fails compilation at 123:35, invoking IWebClient::Create() whereas this arg-less method does not exist, only one with a single URL param.
Am I doing something wrong? I'm not sure I want to start modifying this code.
