Users shouldn't be emailed needlessly

[keysmashes]

People already get too much email; we don't want to make the problem worse.

• Reminders are not very intelligent – when running over a very short timeframe, people get emails telling them to submit their project when the system isn't even available to them yet.
• Reminders can be sent very close together when running over a short timeframe (e.g. 14-day and 7-day reminders being sent simultaneously, if the deadline is set for less than a week away at rotation creation).
• The Graduate Office is bcc'd into every email – is this actually what they want? (also: do users expect that the Graduate Office can e.g. read feedback from supervisors to students, given the access controls the backend imposes on that data?)
