Include this partial in a head section to include basic Open Graph metadata.

Pass a variable `NAME` to give a value for the `og:NAME` property.

These properties are only listed if you give a value for them:

* url: A URL string that includes at least an absolute path.  This partial

  will fill in a default scheme and host if needed.

* title: A string.  Tags are stripped, then the rest is assumed HTML-safe.

* description: A string.  Tags are stripped, then the rest is assumed

  HTML-safe.

These properties are always included.  You can override them but you

normally shouldn't need to:

* type: Default "website".

* locale: Default "en_US".

* site_name: Default "Software Freedom Conservancy"
