Record pay or title changes

Records a pay, title or options change for one or more people on Team (up to 100), each from its effective date. With letter_template_id, each person's letter fills from the company's confirmed change template, is checked word for word and waits as a draft envelope (the officer signs first, the person second with an emailed code, signing or acknowledging as the template says) until team.change.send. One payroll task covers the call; new options open a task for the board's grant. Pay is typed, never suggested, and only members who see pay record it.
