4d6968f95d ProfileViewer: Precompute the timestamp and "in kernel?" per sample 
Instead of fetching these from JSON in every paint event, we now have a
separate "SampleData" vector that can be iterated.

This optimization was made possible by profiling ProfileViewer and then
analyzing the profile with ProfileViewer! :^)

3fd2304dad ProfileViewer: Allow filtering samples in a specific time range 
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.

a3e7c99ffe ProfileViewer: Add a timeline widget for a visual view of the profile 
Userspace stack frames are in blue, kernel stack frames in red :^)
