/* Effects */
// gmcnutt: EFFECT_NATURAL was bit 30, and is intended to be used for natural
// abilities (like snakes spitting venom) so that they will not be affected by
// negate magic. But I ran into a problem: I needed to add EFFECT_RESTORE for
// mana restoration potions, but I found that using a constant with bit 31 set
// did not work out right. The parser uses atol(), which sees the high bit set
// and I think assumes it's an overflow, so it converts the value to LONG_MAX,
// which isn't what we intended. Since I'm basically out of bits something had
// to give, and I sacrificed EFFECT_NATURAL for EFFECT_RESTORE.
//
// During the 0.3.x development line we'll address this issue. A simple thing
// to do would be to start using multi-byte bitmaps and fix the parser. But the
// new effect system may make this a non-issue anyway, so let's wait and see.
