GML options not always applied.

This is a follow-up for https://github.com/openlayers/ol3/pull/711
for the GML parser. Also use goog.array.map instead of map as was
pointed out by @twpayne on the WKT review and update the example data
to use all US states as pointed out by @tschaub on the Google hangout.
