* fixup labels and help_text for the email field * add email and published columns to speaker proposal table, add published column to event proposal table * send email to user when a speaker or eventproposal is accepted or rejected. Send email to submitter and all speakers when an eventinstance is created, or when the time is updated (event is rescheduled). Fix a few other small things while here.
