Restored some orphaned translations.
Orphaned messages file.
confirmDelete (and confirmDeleteAll) already say why a build cannot be deleted (and prevent you from proceeding), so no need to hide the Delete link in this case.
Run.whyKeepLog should be a complete sentence.
Otherwise you get nonsense like this:
Cannot delete this build, because it is #3 depends on this
Run.canToggleLogKeep.
Corrected encoding.
