Limit the range of the missionary's full action but increase its effectivnes.
The missionary could only really be used unthreatened over multiple turns.
Since any unit can be disbanded during upkeep before it is evangelized, the missionary is only a slow destroy effect.
Now it is way more potent controlling cheaper units with the first action but it has to be close to the enemy unit making it more vulnerable.

Translatable properties now have the language as subkey (currently en, de).

generate_card.py takes an optional argument to select the language.

The latex/Makefile has two new targets de and en each building all
cards under latex/cards/<lang> and latex/build/<lang>

Card definitions are now stored in data/cards/ in a subdirectory for each
set as YAML files.
YAML is still human readable but stricter and better to handle in code
than ini.

The latex filesystem layout resembles the card definition layout and
is created by the Makefile from the YAML card definitions and must not
be regenerated each time by hand.
