* Item bonus correction, ambiguous of 'HP/SP Gain' implementation.
* Since no implementation for 'drain HP/SP from target', the bonus was removed but makes 'HP/SP Drain' bonuses act like 'drain HP/SP from target' that was totally wrong.
* This also fixed#471, @AbuGosok
* Removed HP/SP Gain bonuses that should be use HP/SP Drain:
* `bonus bHPGainAttack,n;` is same as `bonus bHPDrainValue,n;`.
* `bonus bSPGainAttack,n;` is same as `bonus bSPDrainValue,n;`.
* `bonus2 bHPGainAttackRate,x,n;` is same as `bonus2 bHPDrainRate,x,n;`.
* `bonus2 bSPGainAttackRate,x,n;` is same as `bonus2 bSPDrainRate,x,n;`.
* `bonus2 bHPGainRaceAttack,r,n;` is same as `bonus2 bHPDrainValueRace,r,n;`.
* `bonus2 bSPGainRaceAttack,r,n;` is same as `bonus2 bSPDrainValueRace,r,n;`.
* `bonus2 bHPGainRaceAttackRate,r,n;` is same as `bonus2 bSPDrainValueRace,r,n;`.
* `bonus2 bSPGainRaceAttackRate,r,n;` is same as `bonus2 bSPDrainValueRace,r,n;`.
* `bonus bHPGainAttackRate,n;` none.
* `bonus bSPGainAttackRate,n;` none.
