Add event type "Outreach"

[bot190]

We should add a new event type for tracking "Outreach" events.

I can fix it in the code, but you'll need to modify the DB to support existing installations. Unless I do some ugly stuff in the init script to check whether it exists...

Can't we add a DB migration that adds the new row?

I've manually added the event type to the production DB. I'll add it to the code as well so it gets created on new DBs (If there ever were to be one).
