Add a setting to retrieve bookmark metadata asynchrounously
- There is a new standalone script (metadata.js) which requests a new controller to get bookmark metadata and fill the form async - This feature is enabled with the new setting: general.enable_async_metadata (enabled by default) - general.retrieve_description is now enabled by default - A small rotating loader animation has a been added to bookmark inputs when metadata is being retrieved (default template) - Custom JS htmlentities has been removed and mathiasbynens/he library is used instead Fixes #1563
