/**
* Set the HTML part of a message object.
* As for all other dc_msg_t setters,
* this is only useful if the message is sent using dc_send_msg() later.
*
* Please note, that Delta Chat clients show the plain text set with
* dc_msg_set_text() at the first place;
* the HTML part is not shown instead of this text.
* However, for messages with HTML parts,
* on the receiver's device, dc_msg_has_html() will return 1
* and a button "Show full message" is typically shown.
*
* So adding a HTML part might be useful eg. for bots,
* that want to add rich content to a message, eg. a website;
* this HTML part is similar to an attachment then.
*
* **dc_msg_set_html() is currently not meant for sending a message,
* a "normal user" has typed in!**
* Use dc_msg_set_text() for that purpose.
*
* @memberof dc_msg_t
* @param msg The message object.
* @param html HTML to send.
