Fixes, PlaceholderAPI Support, & Fabric 1.18.1

Changelog (Bukkit)

• (#67) PlaceholderAPI support. Added new placeholders (credit to @darbyjack)
  • %veinminer_enabled%: Whether or not VeinMiner is toggled on
  • %veinminer_enabled_category_<category>%: Whether or not VeinMiner is toggled on for a given category
  • %veinminer_active%: Whether or not VeinMiner is active (e.g. the player has the keybind pressed)
• (#74) Added NONE as an option for DefaultActivationStrategy. VeinMiner will never active in this case
• (#73) Fixed AntiAura failing to integrate on modern versions
• (#71) Fixed 1.17.1 servers failing to startup properly due to legacy support

Changelog (Fabric)

• Updated to support Fabric 1.18.1, loader 0.12.11
• Dropped support for Minecraft 1.17.x
• Dropped support for Java 16 (as Minecraft now requires Java 17)

While VeinMiner for Fabric is compiled against Java 17 to comply with Minecraft 1.18's required version of Java, VeinMiner for Bukkit (the server plugin) is still compiled against Java 8. This may not be the case in the future. It is advised that you update your version of Java to at least Java 16 if you have not already as VeinMiner will soon use it as the minimum version.
