Merge pull request #26 from ckeditor/t/ckeditor5/1477

Other: Adjustments to new editor initialisation events.
BREAKING CHANGE: The `editor#dataReady` event was removed. The `editor.data#ready` event has been introduced and should be used instead.
BREAKING CHANGE: The `editor#pluginsReady` event was removed. Use plugin `afterInit()` method instead.
