Adds regrade request features to Howamidoing, so that students can request them directly within Howamidoing and staff can resolve them within Howamidoing as well.
TODOs:
[x] run DB migration before building
[x] add logic to email students immediately when their regrade requests are resolved
[x] add logic to prevent resubmission of regrade requests
[x] to allow for cases where the above needs to be bypassed, add a "needs more info" status that doesn't count as resolved
