Subject: Improve error messages and debugging

Work on improving the formatting and quality of error messages

When sail is invoked with sail -i, any type errors now drop the user
down to the interactive prompt, with the interactive environment being
the environment at the point the type error occurred, this means the
typechecker state can be interactively queried in the interpreter to help
diagnose type errors.
