VIP Plugins AxSpawners | All-In-One Virtual Spawners

- Fixed some Folia exceptions.

- Added a %player% placeholder that can be used to display the spawner owner's name within the plugin holograms and guis

- Updated ExcellentShop integration

- The plugin now calculates price modifiers into item prices. (if the shop plugin supports it)
- Added a cache -> shop-seconds setting, which is used to decrease the load coming from the shop plugin searching for item prices.

- Some bug fixes to the world unloading/loading handling. This should fix holograms not appearing if a world is unloaded and reloaded.
