DEVTOOLS: Rewrite create_kyradat.

Now static data is directly stored inside source code files which allows the
tool to generate kyra.dat without any additional input.

This will make supporting fan translations easier, since only the localized
strings have to be added and an appropriate game entry has to be added.
DISTS: Regenerate kyra.dat.
KYRA: Fix EoB 1 German rest string when monsters are nearby.
