Security

• Fix html_safe escaping in Jason.encode

  The <!-- sequence of characters would not be escaped in Jason.encode withhtml_escape mode, which could lead to DoS attacks when used for embedding of arbitrary, user controlled strings into HTML through JSON (e.g. inside of <script> tags).

  If you were not using the html_safe option, you are not affected.
