Turn autoIndentOnPaste off to prevent indent on pasted code

[wingyplus]

To fix #34. I'll disable autoIndentOnPaste for now.

Thanks.

Are there any scenarios where this would be helpful to leave on?

When I have a code:

(defn index-of-any [pred coll]
  (first (index-filter pred coll)))

(foo)
(bar)

When I want to copy (foo) and (bar) to another source file under another code block, I don't want copied code to be indent like this:

(defn do-something 
  foo)

  (foo)
  (bar)
