The `<StatusPrepend>` component:
--------------------------------

The `<StatusPrepend>` component holds a status's prepend, ie the text
that says “X reblogged this,” etc. It is represented by an `<aside>`
element.

###  Props

 -  __`type` (`PropTypes.string`) :__
    The type of prepend. One of `'reblogged_by'`, `'reblog'`,
    `'favourite'`.

 -  __`account` (`ImmutablePropTypes.map`) :__
    The account associated with the prepend.

 -  __`parseClick` (`PropTypes.func.isRequired`) :__
    Our click parsing function.

*/

  static propTypes = {
    type: PropTypes.string.isRequired,
    account: ImmutablePropTypes.map.isRequired,
    parseClick: PropTypes.func.isRequired,
    notificationId: PropTypes.number,
  };

/*

###  Implementation

####  `handleClick()`.

This is just a small wrapper for `parseClick()` that gets fired when
an account link is clicked.

*/

  handleClick = (e) => {
    const { account, parseClick } = this.props;
    parseClick(e, `/accounts/${+account.get('id')}`);
  }

/*

####  `<Message>`.

`<Message>` is a quick functional React component which renders the
actual prepend message based on our provided `type`. First we create a
`link` for the account's name, and then use `<FormattedMessage>` to
generate the message.

*/

  Message = () => {
    const { type, account } = this.props;

      <a
        onClick={this.handleClick}

            )),

          defaultMessage='{name} boosted'
          values={{ name : link }}

          id='notification.favourite'
          defaultMessage='{name} favourited your status'

          values={{ name : link }}
        />
      );
    }
    return null;
  }

/*

####  `render()`.

Our `render()` is incredibly simple; we just render the icon and then
the `<Message>` inside of an <aside>.

*/

    const { Message } = this;

            className={`fa fa-fw fa-${
