Add a refresh button to Performance Counters and Function Details visualizers about slimtune HOT 4 CLOSED

The performance counters visualizer is completely auto refresh. Adding a refresh
button won't accomplish anything.

For function details, there probably should be one...but in general, the refresh
buttons annoy me. On the one hand, the data is shifting under you and the GUI 
can't
go jumping around while you're not interacting with it. On the other hand, the 
manual
refreshes seem archaic when the point is supposed to be true live profiling.

The pie chart can be made auto refresh easily enough. It's that damn listbox I 
need
to figure out. Maybe I can do it the same way I do the performance counters.

Auto-refresh is fine, its just a bit weird to have some visualizers needing to 
be 
manually refreshed and others not.

Yeah, I'd love to have them all auto...but it's tricky for the newer 
visualizers and
borderline impossible for the NProf and thread views without some serious work.

This has been addressed with the new common toolbar in 0.3.1 that displays 
refresh info as needed.
