Fix scrolling in SWF.ListView.EnsureVisible(int index)

This fixes https://bugzilla.xamarin.com/show_bug.cgi?id=22483
[mdoc] New make test for the --dropns functionality
[mdoc] New make test, reproduces issue with --dropns when run with a secondary assembly that doesn't drop the specified namespace
[mdoc] added -dropns-assemblies parameter.
Will now only replace the namespace when the type or member is in a listed assembly
[mdoc] Formatting feedback from pull #1273
[mdoc] consolidated dropns and dropns-assemblies into a single parameter.

Based on pull request feedback, this is a simpler usage, and meets our required use-case. A sample version of this parameter would be: `--dropns MyUnifiedAssembly=MyDroppedPrefix`
[System] Add performanceCounters element to System.Diagnostics app.config configuration section

See http://msdn.microsoft.com/en-us/library/ms229387(v=vs.110).aspx for details about the element.
The value that is set by the element isn't currently used in Mono, but applications using it in their app.config crash otherwise (e.g. http://stackoverflow.com/questions/25741651).
