Transitions final autosave location to `OnTransitionEnd`.
Adds functionality to autosave to set a delayed save flag if AutoSave is set to Major or All Items and one is obtained in a grotto, to avoid grotto autosaving but still provide for the autosave when location-based saving is off.
Fixes small bug with item lookup where sometimes an item's `modIndex` would sometimes be reported one way, but the way Randomizer does things it would be in a the other `modIndex`, and the lookup would fail.
Minor variable name clarification in ItemTableManager.
Modifies AutoSave to account for item ID overlap from `MOD_RANDOMIZER` table (all items in the randomizer table is considered major for AutoSave purposes except ice traps).
