VSCode completion inserts them sometimes (don't know what triggers
that), but inside the SugarCube 'this' is different, apparently.

Fixes #1811.

Change the job id array type to dictionary of string to set of number.
Use IDs in the listings and kill index-based functions in the facility
classes.

VSCode and typescript still do not understand assignments to window as
introducing of a global name. To make them happy, use assignment to
globalThis.

Also some work on completion for TypeScript/VSCode
