[Haskell-cafe] Trouble building library with cabal-install 1.24

[Amy de Buitléir]

Someone with a monad-friendly email address suggested a fix.

1. Delete cabal.project.local

2. cabal new-build --enable-tests

   Finally, the creatur library is built!

3. Run tests:

   dist-newstyle/build/creatur-5.9.12/build/creatur-tests/creatur-tests
