Move the labels above the inputs for languages that don’t fix in the width of the sprite-info pane.

Because of the different widths of everything I left aligned them.

Examples,
Abkhaz, Catalan, Greek.

renamed the `rtl-locales` lib file as `locale-utils` as  it’s doing more than rtl now. RTL should probably move into the scratch-l10n repo, but should the `wide-locales` setting? That seems like something that is gui specific. I don’t like having to hard code the specific languages that don’t fit, but there didn’t seem to be a better way to handle it right now.
