HikariCP config + MaxHP/MP & EXP overhaul + Venom fix

Overhauled the HikariCP connection, now it properly tries the best to hand out a DB connection. Fixed "commands" NPC crashing out players when entering the command multiple times in a short time. Rebalanced HP/MP gain on leveling up/AP resetting. Rebalanced HP/MP loss when AP resetting to use the same amount they would be earning on levelup. Fixed EXP distribution now computing overall monster maxHP plus heal instead of flat monter maxHP, that rendered on distributions of over 100% of the raw EXP. Added concurrency protection on MapleMonster. Fixed an issue on venom skills that would let an "1 dmg" appear to the client alongside the DOT.
