Try to get the `.editorconfig` and `.prettierrc` files as close as possible
to the formatting that was used in Flamenco. Because these files weren't
here during most of Flamenco's development so far, having them caused quite
a few changes in the webapp files.
No functional changes intended.
Show workers with their status, and allow clicking on a worker to activate
it and show its details (which currently is limited to just its ID). Does
include Vue Router handling of the active worker ID and CSS classes for
worker statuses.
This basically copies the `JobsTable` component to `workers/WorkersTable`.
The intention is that all the jobs-specific components will move into a
`jobs` subdirectory at some point.
Status indicators are used in Tabulator cells, and it's unknown whether
we can use Vue components there. Moving the code to a central place makes
it a bit easier to reuse the function in various places.
