STILL DOESN'T WORK but at least it compiles now
fix test

- fix SBT build by moving congeal-test code from src/test to src/main
- write a Makefile rule to run the JUnit test command-line style
playing around with invoking scalac and scala as Java mains
put ApiTest back as a real test and start working on forking scalac

also move Test1.scala since sbt is trying to compile this as part of
project congeal-parent
pull out some logic from Makefile into bin/ivy-scalac and bin/ivy-scala
basic test scaffolding for compiler success and failure cases

I can remove Makefile and Test1.scala now because these have been
replicated in the congeal-test test suite
begin playing around with apiImpl
