Use int& type for argc in wxInitialize and wxInitializer

Other functions that take (argc,argv) arguments (wxEntry, wxEntryStart)
take argc by reference, because they may manipulate the arguments list.
wxInitialize() used passing by value, so any modifications would be
silently lost. Make all the functions consistent in their handling of
argc by using int& everywhere.
