Prevent inconsistent status bar progress reporting states

Merge setting title and progress percent into one method. This
makes sure that the method can be called from all over the place
and will still always show a consistent state instead of partially
showing the progress percent for one progress but the label for
a different one.

This is to enable various tasks reporting progress at the same time
in a way that doesn't lead to a confusing mess for users. Usually
multiple tasks do not show progress at the same time, but when it
happens this commit should make sure that the user experience is
at least bearable.

Allow not having a "Stop" button next to the progress report for
tasks that cannot be stopped.
