Problem: When using LabelLister or similar systems to add labels in new languages or want to find a specific language but don't want to go through 300+ languages, it can be useful to know by which language code the languages are sorted after all.
Proposed solution: Introduced the ability to print the languages' language code in the label box, preferably before the language name so that editors know what that language's language code is.
Who would benefit: Editors who contribute in multiple languages
