Planned Rewrite for Discord.js v13

[NovaLynxie]

Due to new release of Discord.js v13 this bot's main framework module, Commando, has been depreciated and will not be supported going forward. Instead a new framework 'Sapphire' will be used to replace this. Some further changes will also break the bot so some features may stop working entirely.

Things to do:

• [x] #7
• [x] Setup Intents (Required as of discord.js v13!)
• [x] Add depreciation message when migrating from v3 (to v4)
• [x] #8
• [x] #17
• [x] #12

Advantages:

• Uses newer Node version and updated Discord.js
• Allows full functionality for newer features! Disadvantages:
• Requires Node v16.6.0 minimum. Breaks many old features... 😞
• Settings database storage methods may not work. Implemented working solution!
• Dashboard feature will be unavailable till storage method is found. Dashboard reworked and updated!

Removed the following tasks:

- Update command files to match Sapphire command structures. 
Reason: Seems not yet ready / not very well documented yet... will have to use other solutions.
- Rewrite as typescript? (might do since this will be a full rewrite)
Reason: Scrapped rewrite to typescript, lack the knowledge and patience at this time and will delay new version deployment.

All the tasks are finally done. Closed as complete.
