Improve level error handling

### I am planning on implementing this myself

Yes

### Describe your request

Currently maps hard crash if you encounter an exception within them, _except_ when entering from `LevelEnter`, e.g. loading a map from a new savefile. In that case, it opens a postcard informing you that an exception has occurred and returns you to map. I want to look into:
1. Moving this "soft-crash" functionality so it gets called in more situations. Looking first into exceptions that occur during level load, ideally others as well.
2. Improving logs in places that hard-crash with non-descriptive exceptions and stack traces, e.g. autotiler-related crashes.
3. Potentially manually invoking the soft-crash features with specific messages for common crashes.
