Rephrased continue statement skipping over one line.
Updated autocomplete source list on type change.

Some fields are shared among multiple types and the suggestion list must
reflect that.
Removed summary from _view/fields-values.

I never used the summary for anything and the view will help me to speed up
document filters.
Applied reduce mechanism from _view/type-year.

That is, reduce=false has no value at all but group=true duplicates
_view/geojson's value scheme so we can send it through _list/tabulate.
