Fix packetfly config bug

• Fix packetfly config bug, should now actually work.

Prevent PacketFly

• Prevent the future/rusherhack packet fly exploit. It is enabled by default, you can disable it by changing PatchPacketFly to false
• Remove god mode option from config since it's no longer in the code
• Change default chat slowmode from from 3 to 1 due to false positives.

More exploits and clean up code

• Patch dispenser crash exploit bypass
• Patch rusherhack/future/kamiblue elytra fly bypass, disabled by default because the normal speed settings will catch it anyway. However if you want elytras to use durability turn this on.
• Clean up code and optimize imports

Revert only certain items stacks

• You can now revert only certain items from being unstacked by setting OnlyRevertStacksForCertainItems to true! - Requested by STORMIN

Use protocollib and remove godmode patch

• Now using protocollib since the old packet system was dogshit and caused players to get disconnected when the plugin was reloaded.
• Removed the modified god mode patch - Was removed because the original code was so shit that when reloaded with plugman all the players will get kicked, aswell as breaking support for anything other than 1.12.2. Please use my standalone plugin for this (1.12.2 only): https://github.com/moom0o/AntiGodMode
• Reverted smaller jar fix, caused unintended consequences.

Improvements

• Add banned words config option
• Prevent duplicate messages check when message failed to send due to slowmode
• Change crash attempt logger type from info to warning
• Add elytra bursting speed, if the server is above a certain tps, allow your players to go faster on an elytra!
• Ctrl Alt L
• Make jar file size smaller

New crash exploits, code formatting, and more

• Prevent new dispenser crash exploit (Make a dispenser place a shulker at Y 255, server will hang)
• Prevent autocrafting lag exploit (Spamming autocrafting will cause the tps to drop.)
• Move some commands to proper command event instead of preprocess event, will convert all commands later.
• Add /aef reload to reload the config so you don't have to use plugman/server-utils
• Add protocolapi support for later
• Fix chunk checking only checking anything below Y128 instead of 256
• CTRL + ALT + L to format code

Fix config bug and update antispam

• Fixed a config bug where I forgot to edit the line
• Added some more phrases to the antispam to block discord advertisers

Improve stacked items patch

• Check for stacked items on container open

Prevent portal traps

• Prevent portal traps, if players have been stuck for 15 seconds, they will be teleported back.
• Allow ops to bypass elytra limits
• Allow xp to be thrown by players but not by dispensers
