Hey guys, been wanting to make these changes for a while now and I finally got around to doing it!

Changelog:
- added four different colors of Bottles o' XP based off of how many orbs are stored inside them
- fixed a legacy support issue that would come up on server startup

Changelog:

• Added level-based xp potions
• Added new command for creating level-based xp potions, /droplvl
• Added new permission to use the /droplvl command, dropxp.lvl
  • The default value of this permission is op
• Fixed bug with drinking xp potions in your off hand when requireThickPotion is set to false
• Renamed the xp potions to better fit player shops, due to some players having lengthy usernames
  
  • A player made xp potion will now be named "Bottle o' XP", and a level-based potion will be named "Bottle o' Levels"
• Added chat prefixes to messages from DropXP
• Cleaned up and reorganized some code

Change Log:
-Added a permission to allow players to specify the amount of xp they drop
-The default value for this permission is op only
-If a player has this permission, they can use /dropxp <number of levels>
-Doesn't change anything if "requireThickPotion" is true
-Added info to XP Potions that shows how many levels its worth (starting from level 0)
-Changed the appearance of thick potions when they are created in a brewing stand, but only if requireThickPotion is set to true
-Slightly changed the color of XP potions
-Removed the minimum 1 level requirement to drop xp, dropping xp now stores all xp

-Added permissions!
-dropxp.drop for storing xp
-dropxp.drink for drinking xp potions
-dropxp.* for both

Sorry for if these updates are too frequent, this is the first plugin I've ever posted so I'm getting used to how this works Thank you!

Fixed a null pointer exception that can happen when requireThickPotion is set to true

Change log:
-added 1.14 support
-added sound effects when dropping xp or drinking an xp potion
-fixed a few typos
