ChatManager

Fixed:

• Issue with PlaceholderAPI in messages.
• Issue with title messages toggle, we used the wrong config option for the toggle.

Changes:

• Updated internally how messages are handled which includes a safety net if the config gets messed up.
• Added a safety net to config options to ensure the plugin functions even if the config is messed up.
• Prefix is no longer sent in console as you can add it manually to every message.
• {Prefix} is now {prefix}, {Prefix} will work for the time being, but it's recommended you use Find and Replace to change it to {prefix}
