Add springboot template (a simple @RestController)
Merge branch 'springboot' of https://github.com/dsyer/lazybones into springboot
Fine tune the new Spring Boot template.

* Moved the SCM ignores into the post-install script so that they work with
  `--with-git`
* Fleshed out the README a little bit
* Added the `application` plugin to the Gradle build
* Added the missing VERSION file and set template version to 0.1
