Rewrite configuration setup

I’ve been playing around a bit with configuration: https://github.com/tipsy/javalin/pull/507

The general idea is to move away from app.enabledXyz methods, and to reduce the amount of methods on the Javalin class:

val app = Javalin.create().config { c ->
    c.contextPath = "/"
    c.caseSensitiveUrls = false
    c.devLogging = true
    c.requestLogger { ctx, ms ->
        println("${ctx.method()} ${ctx.path()}, took $ms}")
    }
    c.server { Server() }
    c.addStaticFiles("/public")
    c.addSinglePageHandler("/", "/public/subpage/index.html")
}.start()

Any thoughts?

Alternative:

val app = Javalin.create().configure { server, servlet ->
    server.contextPath = "/"
    server.caseSensitiveUrls = false
    server.server { Server() }
    servlet.devLogging = true
    servlet.requestLogger { ctx, ms ->
        println("${ctx.method()} ${ctx.path()}, took $ms}")
    }
    servlet.addStaticFiles("/public")
    servlet.addSinglePageHandler("/", "/public/subpage/index.html")
}.start(0)

It’s not really a feature of Javalin, it’s reading a file and mapping it to a Kotlin/Java object. I see that a lot of people are confused about this, so I can write a tutorial after Javalin 3 is done.
