Calendar Requests

[bgraves49]

Seeing if it's possible to plan a few edits to the calendar

• make it so personnel can RSVP after the event has passed. For people who have forgotten to sign up originally but still showed (or allow the admin to do it on the back end with a manual checkin).
• way to pull a report of who attended what calendar event / how many events they attended / hours they attended, etc
• users can check in or out / upload customized times incase they didn't attend the whole event

To compare, kind of like 'trackitforwards' free plan but it would be nice if it could be integrated into this vs using multiple softwares.

Being added into the system in PR #312. Changes that require app updates (Responder app has calendar support) will be later.
