Patch for G-D-P to accept german Grim Fandango data files for ResidualVM

[Alexandre Detiste]

Thanks applied !

We use the suffix "_alt" only when we can't
decode the logic behind the several version.

Here we can use _prepatched & _unpatched like in ResidualVM code.



I also added  "missing_langs: [es,fr,it]" so that it comes up on
this overview: http://users.teledisnet.be/ade15809/babel.html .

Internal URL of this file is hardcoded in tools/babel.py;
result should go in out/... if someone else find it usefull.

This is currently saved in ascii because by ISP use
a Debian server that never got updated since 2008
with some weird unicode bug. ;-)

So "something else".
