Pretty much what the title says. Closes#1630.
This is a fun little feature that I'm sure many people have always wanted. I can understand that the original authors of Essentials were probably concerned about users entering names that cannot display correctly in the chat, and that is understandable.
I have added a new permission "essentials.nick.allowunsafe", which must be given to anyone who is allowed to use characters outside of the alphanumeric set. The name of the permission is inspired from "essentials.enchantments.allowunsafe", which allows unsafe enchantment levels to be applied to items without guaranteed behaviour. Similarly, the permission "essentials.nick.allowunsafe" allows unsafe characters to be entered for the user's nickname without making any guarantee that those characters will show up in chat correctly.
Allows players to send broadcasts to a specified world by running `/broadcastworld [world] <message>` if enabled.
This is disabled by default in old configs to avoid confusion between updates.
Adds debug logging for `getChatFormat` and `getCommandCooldownEntry`, which makes it much easier to track down issues with group formats in EssentialsX Chat and command cooldowns respectively.
This PR fixes the `unbreakable` attribute on kit items. Previously, Essentials was exclusively using an internal Spigot method to set this on `ItemMeta` objects; however, this solution seems to be non-functional on more recent Spigot builds (1.12.2).
I have altered the `MetaItemStack#setUnbreakable` method to use the native Bukkit method, available for [some time now](https://hub.spigotmc.org/stash/projects/SPIGOT/repos/bukkit/commits/d986a3f), by default. Essentials will still use the old solution as a fallback in case of an older Bukkit version which does not have native support for the attribute.
