[Gimp-docs] Hints for newcomers

[julien]

Hello,

Only a part of gimp-help-2 is updated to v2.4 up now.
If you translate non-updated files, you will miss new features and 
translate deprecated ones.

Unless you update your language directly. In that case, it would be a 
pity not to write the 'en' part also.
Updating is a hard job. Progress is slow. I'm afraid this work will need 
several years.
We are desperately looking for doc writers.

Updated files are listed at
http://wiki.gimp.org/gimp/GimpDocsWip.
