Implement useful ChatManager features

[Parthodys]

Describe the feature

If ChatManager support is being dropped in favor of this plugin, some useful ChatManager features should be added:

• Automatic broadcasts. Per-world / global.
• Anti-Bot. Block players from typing in chat / executing commands until they move.
• Anti-Caps. Prevent messages written in CAPS.
• Anti-Spam. Prevent the chat from being flooded with repetitive messages.
• Anti-Swear. Prevent players from swearing in chat, commands, and signs. (Regex filters would be nice)
• Anti-Unicode. Prevent players from using special chat characters.
• Banned Commands. Prevent players from using certain commands.
• Logs. Chat/Commands/Signs.
• Mentions. Alert/sound when a player mentions another players name.
