Guitars!

Changelog for v4.3.0:

Additions:

• Added a Configuration button to the Guitars! menu (icon looks like a map/paper)
  • Added the option to disable or enable attack mode for guitar items if the player is an OP or if commands are enabled on a singleplayer world or LAN server --> THIS AFFECTS ALL PLAYERS

Changes:

• Guitar model position is now determined by an NBT tag, each guitar can have its own individual position value --> guitar position now displays for other players
• All guitar models have been reworked to get rid of model/texture clashing with the player's arm
• Settings menu layout moved around to reflect other changes and includes page numbers
• Removed/reworked code for better optimization
