feat(bots/discord): framework changes and new features

- Migrated to a new command framework which looks better and works better
- Fixed commands not being bundled correctly
- Added message (prefix) commands with argument validation
- Added a new CommandErrorType, for invalid arguments
- `/eval` is now a bit safer
- Corrected colors for the coinflip embed
- `/stop` now works even when the bot is not connected to the API
