#319363 by sun, quicksketch: Rewrote editor plugin API.  The new plugin API allows Drupal modules to expose editor plugins for ANY editor without implementing editor-specific code.  Major milestone for better content-editing in Drupal.

WELCOME to the next generation of content-editing in Drupal!  8)

#253600 by sun: Changed editor integration so that client-side editors attach to input formats instead of textareas and are invoked for input format enabled textareas only.

#316507 by sun: Added Drupal.wysiwyg function stacks to execute editor library specific actions upon initializing, attaching, detaching, and toggling an editor. Editor specific JavaScript resides in separate files now, as specified and returned by implementations of hook_editor().

Wysiwyg is a real API finally, supporting multiple editors and editor versions.  Yay! 8)
