* Remove launch/* code/tests, as these are in the sbt/launcher project.
* Create a new project which will resolve launcher module from sonatype-snapshots,
and repackage it for the currently building version of sbt.
* Remove ComponentManagerTest which was relying DIRECTLY on launcher classes.
We'll need to reconfigure this shortly to enable the tests again.
Remaining TODOs -
* Update resolvers so people can find the launcher.
* Add ComponentManagerTest back.
* Re-publish the sbt-launch.jar in the location it used to be published.
