Refactor profile command

[cmontminy]

The profile command currently just sends a simple text about rank. It would be better to send a good ol embed and include other info

• Convert the output to an embed instead of a text
• Merge member check function (join date) onto profile
• Merge milestoneCheck function onto profile, show how much more XP is needed to promote
• Include other fun stats that you might run into, go buck wild

here's a cool generator for the embed code !
