Currently the networks are saved rather insecurely

• modstorage should be used instead of serialization into flat files
• the data should be saved more often not just on server shutdown since crashes could cause a lot of lost items.

All of that is now implemented, however the drives should also be written every now and then to properly handle disconnects and controller removals.
