[3.7.0] CustomTabComplete, and bug fixes

RELEASING IT HERE, BECAUSE I REFRESHED SPIGOT UPDATE SITE AND I CANT UPLOAD JAR FILE XD

• Added ConfIgUpdater: Your config.yml file will automatically update, no need to reset your config or manually add missing values!
• Added CustomTabComplete module. This will replace default / which prints every command in the server, with your custom list. NOTE: Enabling this module, will override regular tab-completion, which means, arguments won't work anymore.
• Improved AntiBypass, by removing detections, already handled by proper checks.
• Fixed update checker, sending that you are running an outdated version of the plugin if you updated it to the latest version just after it was updated. Spigot API takes a long time to update values like the plugin version (because this is legacy API).
• Changed look of plugin's GUI. Items now have more descriptions, and overall, GUI is now more readable and useful. Added server information.
• Fixed some modules not working on versions newer than 1.8: LogFilter, update checker, and some other.
• Cleaned up a lot of code.
• Removed Peak/Heuristics notifications on chat. They were slightly useless and just spammed the chat.
