Used fillColor as strokeColor on (Multi)LineStrings.

Also there was kind-of a misspelled corpse in 'options'.
This removes calls to _view/types-fields.

This is work in progress but right now that preserve-field-order feature is as
unstable as it can get. One simple messed-up doc and fields turn out missing
(or worse the view will stall).
Since _view/fields-values has doc.type as first key array element, I just
patched everything to this one.
