Title: remove support for 'ajax_submit'

The idea with 'ajax_submit' was to automatically ajaxify forms; kind of like [PJAX](https://github.com/defunkt/jquery-pjax).

The performance benefit doesn't offset the inconsistency created between an ajaxified button and every other submit button in wp-admin.

In conclusion, it has to go.
