Replace `:use` with `:require/:refer` pair

[nbeloglazov]

There is a tendency to use :require/:refer pair instead of :use. Example:

(ns quil.test-namespace
  (:use [sample.ns1]
        [sample.ns2 :only [hello-world]])
  (:require [sample.ns3 :as ns3]))

should be replaced with

(ns quil.test-namespace
  (:require [sample.ns1 :refer :all]
            [sample.ns2 :refer [hello-world]]
            [sample.ns3 :as ns3]))

I will take this one if you don't mind.
