6.0.0-beta.1

• Added the “License Key” plugin setting, which can be set to a commercial CKEditor license key. (#638)
• CKEditor fields now respect licenseKey values set via their config options. (#638)
• Added craft\ckeditor\models\Settings.
• CKEditor’s control panel JavaScript no longer uses jQuery, Garnish, or the Craft.* globals. It imports what it needs from @craftcms/cp and @craftcms/garnish instead, so CKEditor fields work on a control panel without craftcms/yii2-adapter installed.
• The Craft.showCkeditorInspector and Craft.revAssetUrls globals are now window.CKE_SHOW_INSPECTOR and window.CKE_REV_ASSET_URLS.
• The config options and custom styles mode pickers now render as <craft-listbox>.
• Upload progress is now reported by the upload notification instead of a progress bar below the field.
