Create new verification system

[smyalygames]

Create a new verification to the spec that Stove made.

Features to add:

• Join a VC to create a VC.
• Joining a VC removes all roles (that give access, don't worry about ping/pronoun roles).
• Joining a VC adds a role to the user that won't allow them to access the verification VC again.
• Add a scheduler with the database that tracks when to remove that role that blocks the user from accessing verification vcs again.
• Add an automatic message pinging verifiers with the details (including sus notes) of the user that joined the server and that they want to verify.
• Joining a VC creates a text channel about that user that only verifiers can access.
• Add a timeout if verifier does not join within 15 minutes.
• Send DMs for each timeout explaining when their timeout is over.
• Add welcome messages for after verification has been complete.
• Add a check if a vc is empty on bot start.
• Add the walk through for the bot.
• Add a check when the user joins the server if they have been verified before, give respective roles and even verify block.

Features to keep in mind:

• Have a maximum of 10 verification VCs.

Improvements to add:

• Add a join button in the welcome channel
• Add a message that reminds people about how to verify in #general
• Customisability with the order for the walk-through
• Example questions in the walk-through
• Fix verifier meeting for verifiers when there are other users in the channel. (This is an issue with a verifier being in another verification channel)
• Show how many times the user has been in a verification before
• Prompt to add a sus note after the verification
• Add activism stats - if people talked about industry practises and stuff like that

Being able to skip through verification:
Make so that the stats collected in the database have a possibility of being null, so if a verifier decides to skip, the stats won't be random.
