ProfileViewer: Allow filtering samples in a specific time range

Browse source 
You can now select the time range you want on the profile timeline.
The tree view will update automatically as you alter the range.

Unfortunately this causes the treeview to collapse all of its nodes.
It would be nice to solve this somehow in the future so that nodes
can stay open.
