Dad Bot Doesn't Catch All Missing Permission Errors

[danii]

Dad Bot does not catch every missing permissions error, notably in d!settings. As a result, the errors will typically go straight to the error console.

This is the known list of missing permission errors:

• [ ] d!settings - Send Messages
• [ ] d!settings - Embed Links (Interestingly, needed to send embeds)
• [ ] d!settings - Add Reactions

Also, in some cases dad sends two messages for the same error.
