cabal configure runs much faster than cabal install.
* Create scaffold_test.sh which holds actual tests (still calls scaffold.sh) * Move rm/unregister of foobar to setup/teardown functions * run.sh now prints deprecation warning and calls ../scripts/runtests
Use bash -e instead of single pipeline Unregister foobar after testing it
we haven't really been reaping a benefit from it it doesn't give easy to use output
