Art tooltips: "Verbessert durch" lists what improves each art

Arts are objects (game::Art) built from the game's definitions: name,
launch type, damage source, regeneration group and the skills' art lists.
The tooltip gets one line per effect of a skill or attribute, sorted by
size; unlearned class skills are greyed out at 0%. Weapon arts list only
the damage types the held weapon deals and the held weapon's skill.
Tooltip line wrap ignores colour codes; art tooltips wrap wider.
Blitzschlag's tooltip rewrite becomes a tooltip filter.
