This PR converts the Javscript code of the `ctl` module, into
Typescript, and in the process already fixing two small bugs that went
undetected because... of lack of good type checking.
The linting exceptions are still there and will be removed in the next
PR. Didn't want to change anymore than necessary or Git will detect
these changes as "new files" instead of as "renames".
