Fixes and a change

Fixed the way jQuery is used throughout the plugin. Now uses no conflict
-mode style syntax. Also replaced Advanced Custom Fields plugin with
self made code. Right now only one meta box is there, but more will
come.
Clean up

Cleaned up index.php to just require another php file. Added some
javascript for testing purposes.
Admin side meta boxes

Created a logic to admin side so a user can create meta data alongside
the post.
