Stronger restrictions on has_spirits and has_fire to make the game/UI more user-friendly?

[ymyke]

There used to be these rules in place re has_spirits and has_fire:

• Max one is > 1.
• Neither is == 0, "0-ness" is indicated via some skill such as bloodless or inert or so. (A card with bloodless should always have both has_* == 1.)

Rationale: to keep things simple(r) so a player can rely on default information even if not all information is always displayed.

Later, I implemented the logic where a value of 1 is assumed to be the default and not shown and a 0 explicitly printed as _.

E.g.:

→ Keep this new logic or revert back to the old one that puts stronger restrictions on has_*? (And what influence would this have on potencies, if any?)
