Profiler: Show one timeline per process :^)

Browse source 
Instead of smashing together all the samples into a single timeline,
make one per process and put them all in a ScrollableContainerWidget.

This makes it much easier to see which processes were active and when.
No timeline is displayed for processes with zero samples in the profile.
