dev/7.0.x Bug internationalization translations needed for Edit History

[ekansa]

I'm running dev/7.0.x Arches core with the Arches HER project in order to test some internationalization features.

In the edit history ("Recent Edits") view, there are some missing translations for UI elements, where English is still being displayed for the search box label and display options for entries.

See the attached screen shot

these strings are likely coming from the datatables library, so they will probably need to be translated and then passed to the library on instantiation
