Watcher

- Moved TODO below already completed code

Exceptions

- Renamed `Error` to `ErrorType`
- Constructing a new `TristanableException` will now store the passed in `ErrorType`
- Added `getError()` to `TristanableException` which returns the stored `ErrorType`
- Added two new memebrs to enum `ErrorType`, namely `QUEUE_NOT_FOUND` and `QUEUE_ALREADY_EXISTS`
