Apply Energy Charge Smart Buff to Concentrate/Enrage

Energy Charge currently has a unique way of handling its weapon attack increase compared to other buffs in that it does not completely override any existing weapon attack buffs on the user, and only temporarily overrides them. What this means is that you can use a Coke Zero Pill to increase your weapon attack by 15, fully charge bubble to get 20 weapon attack for 1 min, then after bubble ends you will return to the Coke Zero Pill buff of 15 weapon attack. For any other weapon attack buff in the game such as Rage, Enrage, and Concentrate, assuming you overrode a lower attack buff, after the buff ends you will return to a state of no buffs, or 0 bonus weapon attack.

It would be nice for the Energy Charge buff handling to also be applied to Concentrate and Enrage, to help ease buffing attack in the 2 minute window of downtime during these buffs and make Coke Zero Pills viable on Bowmasters, and Energizers and HT Egg Buff viable on both Bowmasters and Heroes. This would also prevent the need for Heroes to recast Rage at unnecessary times during party play.
