Added React.js like render mechanism

[ertugrulcetin]

When SAtom (special atom type) changes, components which use this satom also re-renders their look.

Simple usage:

(ns seesaw.ex
  (:require [seesaw.core :as sw]
            [seesaw.options :as op]))

(def size (op/satom [150 :by 150]))

(def ff (sw/frame :title "My Title"
                  :size size
                  :visible? true))

(reset! size [300 :by 300]) ;;re-renders UI

@daveray Travis produced: FAILURE: Namespaces seesaw.test.core #'seesaw.core/text can retrieve the value of :caret-position from a widget which I did not understand why?

Why is that?
