Move our internal module into the main package path

I originally put cc.import in a separate directory from the main
modules. This means that programs must extend the package path in order
to import these modules.

However, this ends up being a mixed blessing: while it makes it much
harder for users to accidentally require user code, it also means we
can't expose a public interface which wraps a private module.

Instead, cc.import now lives on the main package path, but lives under
the cc.internal namespace and is not documented anywhere. Hopefully this
should be enough of a clue that one shouldn't use it :p.
