AxPlayerWarps

• Migrated the gui system to the one used in most of our premium plugins.
• That system was based off the one implemented in axplayerwarps, so old configurations should stay fully compatible.
• The plugin now only works on 1.20 and newer versions. (more info: https://docs.artillex-studios.com/supported-versions.html)
• Futher improved handling for world unloading/loading while the plugin is running.
• Added an optional allowed-characters section to use for warp names.
• Added an optional gui auto updater for all guis (in some menus it might not do anything)
• Fixed some other smaller things.

This update changes a of lot things related to guis, if you notice anything not working as it used to, please report it!
