[FEATURE] - Nick storage

[anemoijereja-eden]

What it does:

This feature would allow users to store their current nick in a database, and then use a command to change their nick back to a stored nick on demand.

Who it's for:

This feature would provide a less intrusive method for people who use bots like pluralkit to quickly swap between identities in a guild.

How it would be implemented:

The following commands would be available:

• store - save current nick
• swap - change current nick to a stored nick based on an identifier
• list - show a paginated list of stored nicks
• delete - remove a saved nick

The nicks would be stored as db entries containing the id of the user, contents of the nick, and a short name for it.
