Fix "context not available" in contextless diffs

Summary: D4351 swapped this from a map to a list, and then stopped it from getting to the ChangesetParser so it didn't make it to the Renderer.

Test Plan: Ran "arc diff", copy/pasted it into the web UI. Saw a diff with "context not available" blocks in between missing contexts.

Add the tokenizer.ondemand setting to Core for now.

Summary:
T2255 lists it as "???" and we don't have a "Misc" category and it seems silly
to make it for one option, so stick this in core for now.

Test Plan: Went to the setting page and saw the bool options.
