Reformat messages and add new centralized exception handling (#1417)
* Update and modularize exception handling

cc #1024 #1141

- Stack traces are no longer shown to users unless the --debug flag is
  being used
- Errors, warnings, and other messages contain color as needed
- Converted error messages to Enum
- Adds print_msg function to centralize output (this should replace all
  other output in other modules)
