Changed map chair bonus healing mechanic to be a player skill, instead of promptly available for all players (healing buff takes place only if the player has the skill). Hired Merchant now properly checks for a space on the inventory before permitting a player to buy an item/bundle. Minor fix with concurrency on MapleStorage.
As Suggested by Alex-0000, migrated from DBCP to HikariCP (uses less
external JARs and got a cleaner code overall). Fixed some issues
regarding pets, such as evolving or hatching from egg. Added dojo skills
and fixed energy bar. Added missing upgrade books on drop data.
