adding imageStyle:blockRight

Problem/Motivation

Right now CKEditor shows an option to display an image as "block" wrap text, left, center and right, but not a block right (see attached image).

Steps to reproduce

1. Enable image insertion in CKEditor and enable image align.
2. Create a node with the appropriate text editor.
3. The options are Break Text, Align and wrap left, align and break center, align and wrap right, inline
4. Attempts to add an align and break right with overrides in a module or attempting to patch core do not seem to make the icon option visible.

Proposed resolution

Add an option to allow block right
