Introduction updates

* Add equivelent SQL to the first example
* Add link to Activator template in "What is Slick?"
* Change the features to match the home page
* Add code examples for the features
* Remove the quick overview since there is now a link to the Hello Slick template and we should rely on the Getting Started section to cover that content
Getting Started improvements

* Add Activator templates as the default path
* Replace the dependencies section with info on how to add Slick to an existing app
* Remove reference to example code (Note: We could possibly add references to the code in the Activator template but I'm not sure yet how that would work best.)
