Support newer versions of Minecraft (1.17, 1.18, 1.19)

added configurable cooldown message
added option on whether to display cooldown in actionbar or in chat

Fixed a bug caused by paper.
paper.yml has a configuration option called armor-stands-tick. When set to false, armor stands will always have zero velocity. This plugin relies on an invisible armor stand to represent the thrown axe. Now, that armor stand is forced to tick, even if the configuration property is set to false.

removed offhand usage because it was buggy and not intended

Last update made it so that if the axe is thrown and caught on fire by lava or something, it would also catch anything it hit on fire. This update adds a configuration option to disable that

If the axe is thrown and then caught on fire, the mobs it hits will also catch on fire.

Added 3 new permissions:

mjolnir.use.throw
mjolnir.use.lightning
mjolnir.use.supercharge

new option in config file called "require_permissions_to_use" must be set to true for permissions to work

fixed supercharge ability not having cooldown
