Remove year title from the 'New Records' page title
First attempt to implement uploading records

* Upload mode is an implementation of WP's media-new.php uploader.
* The New mode has a D&D uploader like the media grid and media modal.

Still to do
* Verifying uploaded file
* Processing uploaded file
* Redirecting to appropriate destination (new mode) with JSON
* Read JSON in the new mode, both normal and through AJAX
