Fixed Grandcross and darkgrandcross, should only cause blind against undead race.

Also confirmed that ME, evil land, sanctuary, grandcross/DGC and status recovery are versus element, not race.
Removed confusion effect part from AL_CURE, it doesnt work on official anymore.
Partial revert of signum crucis modification, it doesnt work against players, but work on ELEMENT undead monsters.
