Implement permissions system

[No767]

Summary

This PR addresses #9, by implementing a permissions system with basic hierarchy checks. In addition, the permissions needed will also be displayed in the help command, allowing people to know what permissions they need in order to run the command. As a result, the help command is also being reformatted to accommodate for these changes. In addition, this PR also implements disabling allowed mentions for everyone/here and replied user mentions, and setting up the code to allow for custom prefix support

Before this PR can be merged, there are several items that need to be completed. Namely:

• Implement permissions and injection system
• Remove unused database columns pertaining to hierarchy checks
• Remove perms injection for bot
• Reformat group page to show permissions
• Reformat group page in general
• Document all permissions needed by the bot
