Parlour/Sqoop Integration

Oh, my mistake. I didn't read the `sqoopImport` method properly, and I thought that the API did allow the user the ability to pass in an arbitrary string, using `ImportPath` as a convenience for creating the right path.

So, yes, I am in favour of allowing the user to pass in any old String, but IMO we should have some utilities for creating the right paths in the initial release. It's not hard to add the required methods, and we know what the paths should look like.
