Octal Sun Time 0.2.0

* No location permission anymore. Locations are added by searching for them with wikidata backend. * Multiple locations can be added, one location can be chosen for the clock screen * Locations can be deleted individually or in bulk, and shared with other apps * default clock location is Greenwich until another location is chosen * fixed a bug where the clock would crash on days without sunrise or sunset * the app's layout now also works well in horizontal use
