Improved progress reporting (See desc) (#1125) 

* Separate `--console-title` and `--no-progress`
* Add option `--progress` to show progress-bar even in quiet mode
* Fix and refactor `minicurses`
* Use `minicurses` for all progress reporting
* Standardize use of terminal sequences and enable color support for windows 10
* Add option `--progress-template` to customize progress-bar and console-title
* Add postprocessor hooks and progress reporting
