Initial Update for Slick 3.2

Slick 3.2.0 was released today, and we've update Essential Slick. For now we've used the new profile imports, and made some other smaller changes to avoid calling deprecated methods. In future updates we'll revise chapters to make use of new features, such as mapTo. Use the link below this message to download the updated book. Thanks for supporting Essential Slick.
