Added new configuration section to customise the effects of noise on the message by using regex expressions.

Added a new command /ac noise <entropy 0 to 1> <text>
This is useful to test your configuration

Do be careful when modifying or adding your own regex expressions as they can be tricky and cause unexpected behavior or crashes.

Possible features in future updates:
- discordsrv integration
- new configurations keys that allows you to configure the distribution of a rule. Imagine a graph of entropy against rule effectiveness, it is currently always a horizontal line y = weighting. With this feature it would be possible to warp this line and trigger a rule at a specific range of entropy. An example would be to have different colors for different entropies, i.e at short distance most of the message is gray and from further away it becomes darker.

The plugin was generating a crash when a player sends '$' or '\'. This was fixed by properly escaping the message string with Matcher.quoteReplacement(message)

removed line log.info(format)

Now it may work with plugins like EssentialsX Chat.

- Fixed 'Nobody heard you' bug discovered by Hakaze
- Added the suggested configuration option messageWhenNoListeners.cooldown

As the name suggests, if this option is set to true, ops will always get the original message sent by the player, regardless of distance
