Version 0.9.6

Update: The release had some issues with PostGIS writing and building with GDAL < 2.0 which are now solved.

This release has performance increase for writing files in OBJ and CityGML (file writing is 10-15x faster).

Included is the option for writing CityGML into separate files by using CityGML-Multi as output format. Splitting is done using GDAL->GetLayerName() thus not always related to the input filename.

Included is writing to PostGIS database both in a single or multiple tables (PostGIS or PostGIS-Multi as output format). The PostGIS connection string as used in GDAL is used as output filename in the command line argument (3dfier config.yml -o "PG: host=localhost dbname="3dfier" user=username").
