does client need to receive settings from Engine?

[Khushal, 2016/03/22 04:11:42]

Not right now. Removed that code.

  public:

-  ~TabControlFeature() override;
+  SettingsFeature();
+  ~SettingsFeature() override;

use name consistently? 

"record" --> "download" 

[Khushal, 2016/03/22 04:11:42]

So the name of the web preference is record_whole_document and that's what seems
better for the proto, so it is mapped to the web preference flag name.
I wasn't sure if record_whole_document sounds correct for the client switch
name, I can change it to that if it would be better.
