Subcommands, custom tags, modified discordboosters

[ryandev2]

• Created new directories for impl commands to be more organized, no difference front-end.
• Redid DiscordBoostersCommand to add a small description and use mentions instead of names (doesn't actually ping the user), aswell as include a formatted time for how long this user has been boosting the server for.
• Added a new Tags system, which allows Experts+ to add and modify custom command tags, which anyone can then use.

A general comment, but all the tag logic should go in it's own package in the sys package. So this would include the enum, tag itself, and exceptions.

[Owen1212055]

Additionally, should the tag commands be separate or should it be considered combining them?

Like tag add/remove/edit?

[ryandev2]
