Phase 6: glance widget with cached address

Browse source 
App type changed to widget for glance support. GlanceView shows
event type, date/time, and street+housenumber (or coordinates as
fallback). Addresses are cached in Event storage on first view in
history. Glance-required modules annotated with (:glance). Address
distance threshold raised to 70m.
