RPG Expansion

First Release

Added a basic mana framework (currently not visible but fully functional)

Mana stats are set to 5/5 by default and it regens at a speed of 1 mana point per second

Added commands:

/rpgexpansion <mana> <set> <amount> <player> - set mana for player

/rpgexpansion <mana> <max> <set> <amount> <player> - set max limit of mana for player

(later on there will be a way to increase mana without cheating)

Added Skeleton Talky (Friendly skeleton)

Added Dark Mage (Ranged skeleton that uses magic staff)

Added Dark Boss (Boss, as the name implies...)

Added Magic Staff (Ranged weapon, uses 2 mana per shot, does not have a recipe currently but should be able to drop from dark mages)

Removed Hell Dimension and moved everything from there to the nether as it just works better for now

Renamed the Forgotten Sky portal igniter from "Spark" to "Igniter"
