Title: Fixing saving language file inside a module 

when saving module language file, Autoloader::namespace_path() can't handle the language prefix and as a result the file is not being saved (without any warning btw).
In order to fix that i exploded $identifier to remove the language folder so that namespace::path can find the right module,
and add the language folder later when defining the path (line 174).
