Subject: [PATCH 216/216] Prevent drag-drop of images into TinyMCE

The standard behaviour of TinyMCE is to embed dropped images using data-URIs, which is not desired behaviour.  Ideally, it should upload it to the Moodle filesystem and trigger the Moodle image plugin, but as a first step, this disables the data-URI embedding.
