Goodie Quickstart

//cc @zekiel @mwmiller 
This is a WIP, still have to finish the other half of the quickstart. Needed to fix duckpan for the tutorial to work the way I had planned.

- More pictures to come, we could have one for every step?
- One other alternative is a short video for each step, not necessarily with audio, but a screencap.

My goal is to make it as easy to follow as possible. Given the wide range of experience in newcomers I've tried to assume almost no knowledge in order to get through this. Of course everything could be explained in further detail but it's hard to do that without taking up too much space and distracting everyone.

Any feedback is welcome :)

This PR also updates the "Using DuckPAN" section to match the most recent version of the DuckPAN README which was recently updated.
Whoops! I haven't updated the DuckDuckHack machine yet. Thanks for reminding me! (the button is literally just a physical alias for calling `cd ~/workspace/zeroclickinfo-goodies && duckpan server`
