Add Ekerö for splitting

[matthiasfeist]

Hi.

I followed your instructions in the facebook group and created a split file for Ekerö. Could you please check it and add it? Ekerö.geojson.zip

Thanks! Matthias

I have checked it in now. I found one polygon that was not closed, and two polygons that overlapped, I fixed those two issues before committing. I've made a test run and it looks fine.
