Silent tasks are too silent

[ssbarnea]

When I configure a task as silent, there is no way of knowing what task is really doing because it does not even inform me that it started to run a task.

As we might want to silence tasks, we may still want to display when they start/stop, so we get some kind of progress feedback.

In fact it would be nice if that could even happen on a single line that is rewritten ( \r ended instead of \n).
