Set language files to default value or replacing lost ones

[Mathias Bässler]

Hi,
 
I accidently deleted a language in OM and wanted to reset the files to the way 
they were after installing OM or at least replace the lost language. But if I 
add a new one, I can only specify its name and iso code, not the id of the 
language. Is there a way to add a new language and give it a specific id (then 
import the correct language file of course) so that it can replace the lost 
one? Changing language files etc. is done via language editor, but I don't see 
how it should be done with the editor...
