Measure, weigh and name the European releases' own way (#84)

The French, German, Italian and Spanish releases store Magikarp's
length in millimetres (and print a tenth of them), start the Magikarp
house's record at their own length and holder, keep Pokédex heights in
decimetres and weights in hectograms (printed in metres and kilograms),
read the Heavy Ball's weight byte without converting it, and place the
enemy's nickname before EnemyText (French, Italian) or the trainer's
name before the class (French, Italian, Spanish).

map-revision --symbols writes each release's symbol file, so the
reference specs run against a release; specs that pin English data skip
there.
