Rename app::SelectionSettings to app::UISelectionSettingsImpl

The class UISelectionSettingsImpl is the implementation
of ISelectionSettingsImpl so it doesn't need to be available from
ui_settings_impl.h. Also we can use anonymous namespaces to put classes
that are used only inside ui_settings_impl.cpp.
