    Introduction of a framework for savegame converters, and use it to
    fix a savegame bug in the 0.16 version..
    
    Those converters, composed of piped filter functions, can be
    used to fix bugs in savegames, or to convert from an old version
    to a new one, provided that the changes are not too complex.
    Do not expect this framework to be able to easily resolve our
    well known 'savegame incompatibility' issue...
    
    This framework is used, in this commit, to fix a bug in savegames
    from the 0.16 version, when German language is used (Lua error
    when parsing the .sav file). See savegame/filters_0_16.c for
    more information about that bug.

I'm closing this for now... But if there is something I forgot or which requires
attention do not hesitate to re-open this, though.
