Mixed Line endings in Plans file, on Windows

When running Matsim on Windows, the plans file written contains lines with both Unix (Lf) and Windows (CrLf) line endings because the attributes are written out in a different way (the correct one) from the rest of the information. This is true in 0.9.0 and seems to be the case in the current snapshot too.

org.matsim.utils.objectattributes.attributable.AttributesXmlWriterDelegate.writeAttributes()

uses: writer.newLine()

which writes the newline for the given operating system,

while

methods in org.matsim.core.population.io.PopulationWriterHandlerImplV6

use: out.write("\n");

which outputs just an Lf, regardless of the operating system.

This is fine for Unix-like systems but on Windows, the file has mixed endings.

Thanks for the note. I put it into https://matsim.atlassian.net/browse/MATSIM-843 . Might take some time to fix this since "\n" for line endings is a normal convention for many of us. But I agree that this is not good, and even worse when it is in the same file.
