Initial commit based on spring-boot quick start.

I decided to write an example webapp for Jawbone Up, like I did for Fitbit at https://github.com/MoriTanosuke/fitbit-webapp-example.

And because old things are boring, this time I will write it using Spring Boot. :-)
Ask Jawbone Up API for access.

This will not work until run from an HTTPS host. You can manually replace "https" with "http" in your address bar and continue the process for debug/development purpose, but I need to figure out how to add SSL to the embedded jetty.

Also the access token requests returns "BAD REQUEST"...
