[v5][Lang Suggestion] Ability download langfiles after app!

[Chris59]

I would like to see when you download the langfile you have translated i can download per app and not all the classic suite 

i have several reasons for that and one is you dont get timeout on server when langfile is big and get imported for as an example

Its a huge task translate the suite and woud help alot to just download forum langfiles as an example
