[4.2.3] Detection system rewrite

▶ Changelog

• Rewritten the detections system, which now works way better than before. This has a huge impact on spigot servers (especially 1.8), and a smaller impact on the bungee servers. This update has been tested with a free server.pro server on paper spigot 1.8.8, and free mcspam attack. Before, some bots bypassed the antibot protection and spammed the chat with join/quit and some other messages. Now, most of the bots are blocked, but if some of them still bypass the antibot, you won't even notice they were on your server.
• Fixed the console warning on newer java versions.
• Implemented the 'detections-per-second' condition (which was in the configuration before, but was not used in the code).
