When an event is saved for the first time, broadcast ENTITY_PERSISTED_EVENT instead of MARKER_UPDATED_EVENT. NewMarkerListController listens for this event and sets the marker's isPersisted flag to true, causing the entity type toggle to disappear. Added missing ate.min.js file back to index.html
Alerts and Amenities now also broadcast persisted event instead of updated event when a new entity is saved.
NewMarkerListController: informs ExistingMarkerListController that a new marker has been converted to an existing marker. ExistingMarkerListController updates icon, etc, accordingly.
Left-clicking on a marker after it has been saved for the first time displays the correct entity info. Right clicking opens the edit form. Good to go for events and amenities. Alerts need to be tested
