Remove Unused Code

[Nikolay-Sitnikov]

Removed:

• Clean up command code to make them localized, have autocomplete, and more.
• "Admin Error Logs", which would send a chat message to any admins if something went wrong while loading the configs on game start
• The "All Purpose Debug Command", which does absolutely nothing useful and isn't accessible in production.
• The unused NotificationTickHandler for providing achievement-like popups to the player.
• Moved Avaritia Skullfire Sword fix to Avaritia repository
• Moved "Personal Ender Chest" rename to TXLoader
• Removed the use_machine_metal_tint GT config, since it wasn't correctly implemented anyways and there are better ways to change the machine metal tint color.

To remove in future PRs:

• Move Oil Generation mod-fix to Buildcraft repository
• Move MinetweakerFurnaceFix to a mixin in Hodgepodge
• Debug mode for Custom Drops

Should be merged alongside GTNewHorizons/GT-New-Horizons-Modpack#23384

I am going to draft this PR and split it up into many smaller PRs.

I think there's no need for it, I've looked through every commit, they were split good enough

I am sorry about that. Feel free to approve the individual PRs, though!
