Fix missing randomized data in spoilers

[mracsys]

Fixes #1962 and fenhl#23

Currently, world initialization uses a reference to the global settings object. Settings with the random option are randomized to a "real" value in the world constructor. This mutates the world's settings, which in turn mutates the global settings object.

If the global retry is triggered, the randomizer will rebuild the worlds from scratch. Instead of re-resolving random settings, the settings remain as they are since they aren't set to random anymore. For filling the world this is fine. However, resolve_random_settings also builds the randomized_list property that is referenced when building the randomized_settings section of the spoiler. Since settings like starting_age and starting_tod are no longer set to random, they are no longer picked up by randomized_list for display in the spoiler. On top of this, the settings section of the spoiler is derived from the _settings key of the distribution, which is a copy of the original settings pre-retry, so this will still show random in the spoiler settings instead of the resolved value from the world.

This only really comes up with multiple ER settings enabled on the main branch, but it can happen if global retry is triggered. It's more common on dev branches with more ER options that are more difficult to roll successfully.

The easiest fix to this (this PR) is to copy the settings in the world constructor so that the initial value is consistent on global retry. However, this will likely not retry the same settings if any of them were randomized, which could lead to certain random settings combinations being less likely to show up in the final output.

An alternative that would always preserve the same settings for retry would cache the randomized settings in global settings on a per-world basis, maybe _randomized_settings to mirror the already existing _settings key.

I think it might be a mistake to allow the randomized settings to reroll, if that's what's happening. You basically explained why, but, I have no idea how serious of a problem it might be.
