This Pull request includes:

• Compatibility for Docker for Mac/Windows
• Configures Jenkins to talk to Docker through a Proxy container to work around TLS Certs (DO NOT USE IN PRODUCTION INSTANCES)
• Simplified startup, sync source, make build, make run... GTG!
• Updates to latest Jenkins 2.58
• Updates to latest plugin versions
• Has default test image/jenkins job to test and make sure everything works
• Utility scripts to help export job/jenkins configuration and reuse it if you lose your data container
• Utility scripts to help export Secrets/Credentials (USE CAUTION: Do not check in protected creds!)

I've maintained the tutorial repo's so the blog is consistent. I will probably update the blog series to just use this methodology in the future. Thank you everyone for your patience and feedback!

@maxfields2000 I think you forgot update the README file correctly: the new version still use Yet Another Docker Plugin or use JNLP instead.
