Another minor favicon fix.
Bugfix: observed_on_string with CEST time zone wasn't working.
Bugfix: performance issue on calendars/show for large places.
Tried to normalize accented search queries.
Made it so other people can add observation field values.
Made place autocomplete rely on sphinx, added more default sphinx conf.
