So, more little things today..
Spall can now show thread/process names from chrome's tracing format, scroll stats, pan while you've got things selected, and read/display the juicy bits of chrome's sampling profiler data.

If you're sick of waiting for the chrome performance tab's profiler to zoom at 0 fps, trying to see what's taking so long in your JS code, you can now load them into spall.

Thanks to @bvisness for doing some serious groundwork figuring out the format.

My sampling profile import is a little beta because it's an undocumented format, so results may definitely vary.
