Example update: Ensure a clean FileBrowser look

[tcrowson]

By default (at least on my setup with 2012), the look and feel of a QFileDialog is a weird blend of the Windows and Softimage styles. But this is easily corrected using the following code at the point of calling the QFileDialog().

def launchFileBrowser(self):
desktop = Application.Desktop
desktop.SuspendWin32ControlsHook()
self.fileDialog = QFileDialog(self)
sourceDir = self.fileDialog.getExistingDirectory(None,'Choose a directory')
...
desktop.RestoreWin32ControlsHook()

Thanks to Luc-Eric Rousseau for pointing this out!
