Command Revamp

[p5nbTgip0r]

Summary:

• Convert to Cloud for command framework
  • Dependant on https://github.com/reddit-diabetes/diabot/pull/132
  • Slash command support would be nice to have, but support must be added into Cloud first
• Modify .gitignore to exclude .idea/
• Nightscout graph command (https://github.com/reddit-diabetes/diabot/tree/bde57af3f9fd012bf75e9a356b19af2d4971990b)
• Some other things I've probably forgotten about?
