Title: Busy Waiting Progress bar

I added a busy waiting mode for situations where it is unclear how long it takes until the process can continue.
It is possible to activate it when the progress bar is created or somewhere in between. The busy waiting mode ends automatically after calling tick again. One can also stop it via calling stopBusyWaiting.
