Linux - Won't start due to missing required directories

[jpts]

The application wont initially run due to missing directories...

Exception in main thread: ~/.factorio/fmm is not a directory.

java -version
java version "1.8.0_73"
Java(TM) SE Runtime Environment (build 1.8.0_73-b02)
Java HotSpot(TM) 64-Bit Server VM (build 25.73-b02, mixed mode)

This is using the version compiled from f3c63893ad41eadc0e12179c43a23012a36003e0

I worked around this by temporarily creating the directories and then changing the settings once the program had loaded.

PS: Many thanks for your work on making this work on linux. Much appreciated :)
