[Feature Request] Add new moderation commands

## **Is your feature request related to a problem? Please describe.**
Before i jump into specific features, i'd like to state that i've been using and thoroughly enjoying the plugin so far. The suggestions below mainly aim to enhance the overall functionalities of the plugin and add few more moderation features which are currently missing.

## **Describe the solution you'd like**
These suggestions consist of:

- ### **New/chatregulator mute [server] command**
Allows server admins to toggle the chat cross servers; enable or disable chat messages to be sent on specific servers. This can be very useful at times where chat gets messy. The above includes the introduction of 2 new permissions, the permission to use the command (chatregulator.command.mute) and a permission to bypass the mute and chat while messages are disabled (chatregulator.bypass.mute).

- ### **New Discord Integration**
Provide a build-in or external compatibility to send Chat Regulator's alerts and punishments to a configurable discord channel. The webhook, would include several useful information in regards to the check (violation) as well as several player information you deem relevant.

## **Additional context**

These suggested features would improve the overall experience of using the Chat Regulator plugin and have been heavily considered on both both players, administrators and plugin developer & contributors in mind. I'm eager to hear your thougths and feedback regarding these suggestions. Thank you for your time and consideration.

Kind regards,
ImDarkLaw

Look at the existing command structure in the ChatRegulator plugin to understand how commands and permissions are registered. Examine the plugin's configuration and event handling to see where chat messages are processed. For Discord integration, research how to send webhooks from a Java plugin and where violation alerts are currently logged. Determine what player data is available at the point of a violation.
