Parse headers from template
Parse the processed template for headers and populates matching header editors accordingly. Those are then stripped from the template body before prepending it and remaining header fields to the composer content. The motivation for this is keeping receiver, sender and subject lines in the template file and generating the message subject with the date functions.
