Components + API tuning

• ktoa.components has a wrapper for every React Native component

(ns app.core
   (:require [ktoa.components :refer [view text switch]]))

(def node 
  (view {:style {:width 200}}
    (text nil "Hello")
    (switch nil nil)))

• ktoa.om - has all needed workarounds for Om-Next
• ktoa.core and ktoa.repl refactored and became more reliable
