Added support for Spigot 1.18.x

Tested it myself but if there's any issues let me know (not in the review section, but in the discussion part, please <3 )

After losing the previous plugin source I've finally sat down to develop an 1.19 version!

Lots of stuff is different under the hood, no hacky NMS stuff anymore, everything is done via the Spigot API.

I'll update the main page with all features and changes (and a new video!)

Changes:

- Squashed a bug where all levitation effects were removed from players even if they last for only a couple of seconds (from other plugins for example). The effects will only be removed now if it lasts very, very long. (ie: infinite).

Bugfix:

- Players will no longer take fall damage when they drop from considerable height while holding a Cucco.

Changes:

+ PlaceholderAPI support

• You can use %cucco_playerkills% and %cucco_cuccokills% to get both numbers to display in other places.

+ Peaceful Cuccos are now able to be picked up!

• Right-Clicking one will put it on top of the players head and will give levitate/slowfall when not on solid ground.
• Add "canpickup: true" and "pickuprange: 3" under the "peacefulcuccos:" section to enable this. (or let the plugin generate a new config.yml)

I hope I fixed all possible issues with the Cuccos as players carry one, but please let me know if you find things that don't work/give errors. I'll try to fix it as soon as I can!

Please note: When players are holding a Peaceful Cucco, they can not interact with any other objects. Sneaking will let the Cucco jump off.

Changes:

+ WorldGuard support:
Set the "spawn-cuccos" flag to "true" in your prefered regions and Peaceful Cuccos will spawn instead of normal chickens.
Add "useWorldGuard" under the general section in the config.yml. (or let the plugin create new one)
- a bug where sometimes killed Cuccos would not count as a kill.
- Ganon

Alright! First update ever!

- A few inconsistencies in the code
+ The ability to rename the Peaceful and Angry Cuccos
+ Asetting to change chickens that would spawn into Peaceful Cuccos + a percentage chance of that to happen
+ Cuccos are now aware of arrows or sweep attacks hitting them

Downside: You probably will want to remove your config file and let the plugin generate a new one.
