Subject: Disambiguate Choice::set_values brace-init in PhysicalPrinterDialog

wxWidgets 3.2 added an initializer_list<wxString> constructor to
wxArrayString, which makes a braced initializer for Choice::set_values
ambiguous between the std::vector<std::string> and wxArrayString
overloads. Spell the std::vector<std::string> form explicitly.
