Refactor imports to mirror those of Http4s

[bryce-anderson]

The import style of Http4s has been changing, and I think rho should follow suit. Here is what I propose:

import org.http4s.rho._              // all important types should be in scope
import org.http4s.rho.Rho._          // all batteries included

That would duplicate the Http4s imports, but we may deviate some. First, our route building is based on a trait, so we could include many of those imports in that trait automatically.

Sounds good, maybe I try it in a topic branch?

Go forth and conquer, @before!

[bryce-anderson]

@before, are you still interested in tackling this one?

[arouel]

@bryce-anderson Obviously I have not enough time to start with it. Sorry for that. You should take this one if you have time.

Commit 3c35b1c brings us in line with the core dsl, I believe. I just pushed that to master as it was so simple, almost too simple.

Great, thank you
