Remove org-install it is deprecated

It was causing a warning every time emacs started.
Remove `:autoloads nil' from org-mode recipe

Per jd's suggestion on github,[1] I verified that this can be removed.

After cloning my repo into /tmp/el-get/el-get, I started emacs with
the following bare-bones .emacs file:

    (add-to-list 'load-path "/tmp/el-get/el-get")
    (setq el-get-dir "/tmp/el-get/")
    (require 'el-get)
    (el-get 'sync '(org-mode))

and everything performed as expected when a new Org file was opened.

Add recipe for smartparens
Use original repository for smartchr recipe

It seems this recipe uses emacsmirror from the very beginning.
We should use the original repository if it is maintained.
