Fixed nullpointer exception

Now you can set a condition for receiving the message

Also fixed an ugly bug with EssentialsX nickname system

Now you can use condition in the new "advanced" configuration section

Now you can use hex colors and gradient in the chat format, not only in the message written by the player

The title is self-explanatory, you can now format your message even more!!

Rewrited the default ChatColor.getLastColor because it does not support hex colors

Fixed a bug where username and chat message were not colored properly

Just fixed a typo

Changed all the chat formatting with Adventure TextComponent
Added the ChatHoverEvent when hovering a player's name (you can change the message that will show in the config.yml)

Upgraded command framework

Fixed another inheritance bug

Added a default format.

The plugin will use the default format if the player's group is not defined in config.yml

CONFIG REGEN REQUIRED!

Special thanks to leguernic

Added dependecies in "plugin.yml"
