Profiler: Add a new "Samples" view to the main UI

Browse source 
You can now view the individual samples in a profile one by one with
the new "Samples" view. The "old" main view moves into a "Call Tree"
tab (but it remains the default view.)

When you select a sample in the samples view, we show you the full
symbolicated backtrace in a separate view on the right hand side. :^)
