Message configs are now selected based on the client's language (can be
toggled in the config) and will use MineDown formatting to allow
display of component messages as well as usage of RGB colors in 1.16.
If found the legacy local.yml will be used instead of the per-language
files. Move your local.yml to the correct lang config to if you want to
use the per-client language option.
Version was also changed to 3.11 due to the many internal changes that
have accumulated over time
This is due to a bug in CraftBukkit not properly supporting localised/translatable display names when serialising item meta.
This also adds/improves the message when no valid item ID could be generated.
