Message.ViewContentLink can't be set

[quentinvernot]

When sending a transactional message with the mandrill API, there is a flag, view_content_link, that can be set to tell mandrill to discard the sent message's content so that people who can access the logs can't click on "View content". This flag is true by default and must be hard-set to false.

However... the Message struct declares this field with omitempty, so you it won't be sent when set to false.

type Message struct {
	// ...
	ViewContentLink  bool  `json:"view_content_link,omitempty"`
	// ...
}

Removing omitempty would mean messages would always send view_content_link: false, it's a go quirk, I'm not sure if there is an "elegant" way to fix this. Maybe with a pointer to bool?
