[2.0.15] Factorio is loading the save, even if the checkbox is not selected

This is still occurring in [2.0.15] for both Single player saves and multiplayer saves.

I made some cleanup, as the "what to do after restart" logic was a bit messy.
This resulted in the correct behaviour that when you synced mods from this screen, it just did nothing after restart, as this functionality was never properly implemented.
Yes we have this "auto host" after sync when you press continue, but this just hosts the same way as you did the last time, but in this case, you are supposed to go trhough the "server settings screen" after the load dialog, which would be skipped, and might be wierd, especially if you didn't host before.
This is why the "host-interactive" command line option and related machinery was added so when you restart from before trying to host, it will continue into the server settings dialog with the save already selected after restart.
On top of that, there was missing piece of logic for this case, which would automatically ask for syncing mod when some of the mods in the save were not present, which was also added.

TL;DR done for the next release.
