New line in CSV-Exporter

[BUG] when exporting from CSV by CSV Exporter a Bug occurs in the case an entity has new lines inside f.e. a description field. IF any attribute has a text field with new line "\n" then in exported csv also a new line is generated.

Fix: either convert the \n to another coding or replace \n before exporting.

Reproduce: simply create a new device. Write a mutliline description an export it.
