Conflicts:
cura/Settings/MachineManager.py -> rowCount vs. count
resources/qml/ExtruderIcon.qml -> Someone changed stuff that I had overwritten.
resources/qml/Menus/ConfigurationMenu/PrintCoreConfiguration.qml -> Someone changed stuff that I had removed.
resources/qml/Toolbar.qml -> Git was wrong, not a conflict.
resources/themes/cura-light/theme.json -> Git was wrong, not a conflict.
