New `action_type` values were recently added in the Events API: `approved`, `accepted`, `opened`, `deleted`.  This change adds the new types to the ActionType enum.

A 'scope' attribute was added to the Events API that allows retrieval of all events for a user across all the projects that user has access to.  This change adds support for this new attribute.
