0.8.5 - simplified pom.xml

A tiny improvement: Previously the dependencies in pom.xml were scoped as provided. Now we have removed the provided scope, and so, you won't need to re-mention Spring Lemon dependencies, e.g. spring-boot-starter-web, in your project. Those will come in transitively. The Creating A New Project chapter of the getting started guide, as well as the video tutorial is updated accordingly.
