Daniel Thies dc9ca4acea MDL-46387 editor-atto: Toggle sub/sup tags using rangy
In order to have a consistant browser behavior and prevent nesting of
subscripts and superscripts, tags are converted to CSS classes and then
the CSS classes in the selection are toggeled using the rangy crossbrowser
selection library already included in Atto without using an execCommand.
