Add tut contrib module (#464)

* Add tut contrib module

* Add TutModule tests and documentation

* Use Path instead of PathRef for tut target directory

* Use the correct scala version in TutModule

* Ensure resolving tut doesn't bring in extra scala-library jars

* Ensure MILL_VERSION system property is set in tut tests

* Fork to run tut to fix classpath problems, add test with library usage

* Follow convention w.r.t. publishVersion in testArgs

* Add Scaladoc to TutModule

* Don't supply a default version of Tut

* Update docs to account for mandatory tutVersion setting

* Inline tutArgs, otherwise Tut does not recompile when sources change
