Optional Disable Drop & Drop TinyMCE 4.0 Upload

[Howdy_McGee]

The Main Problem

Currently there's no real way to remove the drop and drop functionality on the default editor. We do have this option with wp_editor() by setting "drag_drop_upload" to false. You would expect to also see this option in a filter like "tiny_mce_before_init" but we don't. I purpose that we add this option so it can be filtered out if needed.

Example of Why The Above is A Problem

I bring this up because on one of my sites I've added an extra custom media upload button which opens a light box. It is supposed to let the user upload images from their computer and I do some custom stuff to them etc. but when the user drags images to my lightbox, the Drag & Drop functionality from the editor seems to take the highest precedence.

Drop and Drop Editor Taking Precedence.

Sounds like we need a filter on _WP_Editors::parse_settings().

I added a patch to #24472 that should address that ticket and this one at the same time. If necessary the changes could be split into separate patches.
