Add script to deploy code to RPI

[jbewing]

This WIP PR adds a script to build and deploy the repo to the raspberry pi. This is potentially nicer than just doing a git pull and manually staging files on the RPI as one would not need to create a branch in version control to do a quick QA test in the RPI environment.

Running

Run ./deploy.sh from the project root

• Requires yarn to be installed
• Requires a unix-like environment with bash, rsync, and ssh
• Requires that you've set up public key authorization over ssh for the RPI (takes 5 minutes + keeps passwords out of version control)

Testing

I've played with this a lot and there are quite a few bugs around the exclude list for pushing Django projects. I plan to keep working on it / evolve it to be bullet-proof, but would appreciate feedback on the approach.

This is pretty stale. Just going to trash it :/
