Prepare mods for factorio.zone

prepare-mods.ps1

# What is this?
#
# This is a script I wrote to automate the process of removing images and soundfiles from mods,
# so that they can be uploaded to factorio.zone without taking forever or even exceed the max-upload size.
# It also creates a mod-settings.zip so that your mod-settings.dat (Startup Settings) are available on the server.
#
# How to use 
#
# Download the script and put it somewhere on you harddrive, e.g., C:\temp\factorio
# Open a powershell prompt "Win+x, i" or just type powershell in the startmenu.
# Navigate to the script (e.g., "cd C:\temp\factorio") and call it like this ".\prepare-mods.ps1" alternatively you can double click on it.
# 
# If you get a Warning regarding execution policy you can start it like this (without the quotes obviously):
#
# "Set-ExecutionPolicy -Scope Process -ExecutionPolicy RemoteSigned; .\prepare-mods.ps1"
#
# This will prompt you regarding the execution policy change, and you have to allow it.

@Kurochi51 which PS version are you using? You can check with $PSVersionTable if you also have something < 5.1 then I might have to add a version check.

I have 5.1

@Kurochi51 I'd suggest to run the script with -Debug maybe you have some invalid data in your mod-list.json
