[gcompris-devel] Release 4.0

[Bruno Coudoin]

I just released gcompris 4.0 Final

The main changes are:
- watercycle.py: now tux must have a shower. 
   to access python games, you need to recompile the tar.gz file with
   the --with-python option.

- railroad: use item group to simplify code. Fixed bug where train
              goes faster and faster after each 'repeat'.

- drawing: In draw activity, now there is much more images.
- erase: more animals from Daniel LE BERRE
- added slovanian support and translation from damjan kovac

And of course translation updates.

Bruno.
