Support doc / source

[betabrain]

I find (doc ...) and (source ...) very convenient for quickly looking stuff up. Unfortunately they don't work in Gorilla.

Is there a way to automatically extend the default workbook as follows on startup:

(ns khaki-grove
  (:require [gorilla-plot.core :as plot])
  (:use [clojure.repl :only [doc source]]))

I would generally like to avoid adding more imports to everyone's code automatically. If you find a way to make this an option/config flag, let me know--it does seem useful.
