[PROJECT IDEA] events calendar

Rationale

We discussed having a public IATI and related events calendar that is easy to add things to so that people can check in one place

Sign up to google - either with codeforiati'atsymbol'gmail.com, or with calendar'atsymbol'codeforiati.org
Set calender to auto-accept invitations
Send invites to (cc also) calendar email address to add them to the calendar
Embed calendar on calendar.codeforiati.org
Offer subscription for people to add it automatically for their own calendars
If getting calendar spam (although hope not if email not that public), have an email rule to only accept emails (and I think therefore invites) from certain email addresses

Can integrate google calendar with Slack channel to all get reminders
See if we can subscribe to the IATI Secretariat/DI calendars if they have them as a good source of events
