Description

This is a POC for #1371. It adds a sub/dub column in the history file so -c knows whether to continue subbed or dubbed. It is not thoroughly tested. It should work with old history files (without the sub/dub column). The current behavior (in this PR) is so that if you switch between subbed and dubbed, the history file should reflect the latest switch. If we want to track subbed and dubbed separately, a change can be added to allow for that.
