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 changes events to store the database Account instead of an OfflinePlayer and deprecates any event method that uses/returns OfflinePlayer. This is necessary as Bukkit#getOfflinePlayer(String) queries Mojang for the UUID when the user was not found in the local cache. As we already store this information (name to UUID mapping) in our database we should not have no need to rely on querying Mojang. (This might make transactions fail for shop owners that haven't played before but that shouldn't really be an issue in most cases)
