- Added support for updatable messages (`updateMessage`), see [README](https://github.com/AnnikaV9/hcclient#updatable-messages-)
- Added `--timestamp-format` option
- Added timestamps to client messages as well
- Use `level` instead of `uType` for checking user type as it's scheduled for removal from hack.chat
- Remove use of `tput` as it breaks scrolling, which is essential
