Project MMO

Added: Effects as sources of XP

Added: unedited files from genData are now ignored on load

Added: "/pmmo store" to store skills in eponymous scoreboard objectives

Added: Attribute perk that uses an attribute's ID.  can be used to replace previous attribute perks.  uses flat calculations of level * per_level.  (new perk file generations use this instead of the old perks.  they are deprecated for removal)

Fixed: Dynamic Trees crash (DT no longer uses AutoValues system)
