Eugene Yokota 08eaba9107 Add SbtPlugin
Fixes #3538

This brings in `sbt.ScriptedPlugin` as `sbt.plugins.ScriptedPlugin` into sbt mothership.
In addition, `sbt.plugins.SbtPlugin` is added that enables the scripted plugin and `sbtPlugin := true`.

This allows plugin authors to bring in scripted plugin by writing:

```scala
lazy val root = (project in file("."))
  .enablePlugins(SbtPlugin)
```
