Add 'punish' filter and automatic banning functionality

Extended the RegexManager filterText method to include a 'punish' case that triggers an automatic ban for users who violate the filter. This commit also updates the PluginMessageListener to handle 'punish' commands, thus completing the execution of an auto-ban function.
