Subject: Asynchronous retrieval of bookmark's thumbnails

This feature is based general.enable_async_metadata setting and works with existing metadata.js file.
The script is compatible with any template:
   - the thumbnail div bloc must have  attribute
   - the bookmark bloc must have  attribute with the bookmark ID as value

Fixes #1564

from fork awesome)
  - This link generates a private key associated to the bookmark
  - Accessing the bookmark while logged out with the proper key will
display it
