Add "sampling profiler" preference, simplify data display when it's set

• Component: Web Inspector (Deprecated)
• Status: RESOLVED FIXED

[Mikhail Naganov]

When a sampling profiler is used, it differs from an instrumentation profiler in two ways:

- first, there is no data for 'calls count' and 'average call duration' data grid columns;
- second, displaying fractions of milliseconds is meaningless, because a sampling profiler can't provide such accuracy.

Thus, my proposal is to introduce a corresponding preference, and to update profiles panel code as necessary.

samplingCpuProfiler should be samplingCPUProfiler per our style guidlines.

Add an empty line before the if.

Opps. Sorry I missed this earlier..

+    if (Preferences.samplingCPUProfiler) {
+      delete columns.average;
+      delete columns.calls;
+    }

You need to use 4 space indents.

Indentation fixed

Oh, I'm really really sorry. I should have different editor settings for WebKit patches.
