refactor/simplify scalaJs plugin and example

- Restructure code as 1 library case class and 1 Build mixin trait. A library is generally easier to understand and could be re-used independently. 1 trait seems simpler than several here.
- Let not the plugin create the multi-project build, but the user project manually. I think while this adds some minor code overhead it is much simpler to understand. Fewer tasks and other moving parts needed.
- Remove verbose nested sbt-style folder structure. It's simpler without it :).
