The structure of some language packs is very outdated, leading to
missing user interface text when using these packs.
Developed a Python script to sync the structure of all language packs
against the master pack (English) so that each pack has the latest set
of localisation strings.
Note that synced items will still need translating, this commit just
ensures that all language packs have the same structure.
Fix#1062
