Title: Remove legacy app.configure() method from app template.

Quoting from the [app.configure() documentation](http://expressjs.com/api.html#app.configure):

> [...] This method remains for legacy reason, and is effectively an if statement [...] **not** required in order to use app.set() and other configuration methods.

So removing this unnecessary legacy method from the new application template seems like the right thing to do.
