#1426 Untranslatable strings remain after translation

[E.Du]

Several menu entries or labels remain untranslated when all the strings are translated using the I18n plugin. See joins UntranslatableStrings 2020-05-25.pdf.

[Gerd Wagner]

Several property files were missing in the I18n administration's bundles table.
These are now included.
Beware: Some of these files contain properties that must not be translated.
Please see and heed the red warning above the bundles table.

The fix is committed and will be available in a new snapshot soon.
