HTML5's drag and drop has a ton of benefits and a couple of
limitations. To achieve a native drag marker, an image tag helper
is used to indicate the size of the relocatable node. Chrome
shades the marker gray natively, Firefox is styled to match.

Objective:
Generalize the shield and phantom magic, so we can use it for pretty much
any node we like. Usually this will be used with generated content nodes,
but also with aliens (of course) and possible other stuff in the future.
Bonus:
Also fixes a bug in DM that would crash VE when you selected to the end
and hit backspace.

*.php
* Added links to new file

ve.ce.MWImageNode.js
* Moved addClass to initialization section of constructor.
