NOTE: This update includes a config version change. Your old config will be backed up to config-old.yml and then the plugin will be reset to defaults.

Updated to 1.21.4

Added new commands:
- /dropsoverhaul addblock <block> - Adds block to dropsoverhaul block list
- /dropsoverhaul removeblock <block> - Removes block from list
- /dropsoverhaul list - Lists blocks in dropsoverhaul list

Fixed an issue where config files were getting reset after restart.
