EPS: Save As options are menus with readable names, and Export As's Range shows an example

Save As to an EPS file showed Preview Format, Overprints and Flattener
Preset as text fields holding their ids (tiffColor, preserve, medium),
the PostScript level as a number field, and labeled every EPS option
except Use Artboards from its name ("Cmyk Post Script", "Thumbnails").

The dialog now shows the options Export's EPS Options shows. Preview,
Overprints, Flattener preset (the built-in presets, then saved ones) and
PostScript are menus of readable names. Transparent and Opaque apply to
the color TIFF preview only. Embed Fonts shows checked and disabled. The
PostScript level comes last. A pick writes the same values as before
(previewFormat "tiffColor", a built-in preset's id, a saved preset's
name, the level as a number). A value that the save would reject shows
as it is.

Every option the dialog shows has a written label. "Preview:" has a row
in every catalog, and the de, it, ja, ko, uk, vi and zh-hant catalogs
gain the menu names, which Export's EPS Options also showed in English.

Export As's Range field shows the "1-3, 5" example when emptied, as
Save As's does.
