Pl3xNPC

Fixes:

• Fixed: Only allow certain mobtypes instead of all entities
• Fixed: Removed ProtocolLib dependency from plugin.yml which prevented plugin from starting up
• Fixed: NPCs no longer disappear when going out of range, changing worlds, or logging out
• Fixed: NPCs now look directly at your eyes instead of guessing the top of your head
• Fixed: Setting a mobtype to "none" or "player" now works (will remove the mob type)
• Fixed: ArrayIndexOutOfBounds error when using the command /npc set lookat
• Fixed: Client no longer crashes when NPCs created/renamed with names longer than 16 characters
• Fixed: NPCs are now truly removed from memory when using the /npc delete command

Additions:

• Added: Mob sounds when selecting them.
• Added: NPCs are auto-selected when created.
• Added: Better inventory system for NPCs (for future usage)

Other:

• Removed useless EntityType saved data (uses MobType instead now)
• Changed the MobType code logic
• Cleaned up code format a bit.
• Spoutcraft support is now completely removed with no plans of bringing it back (Sorry Spout team, you take too long to update... 2+ months?)
• Rewrote the NPC inventory logic (more reliable now, plus adds ability for future expansion).
