rework how cards are defined and generated

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.
