Add a flag to let wxApp::GetRegisteredClassName() register just a single Win32 class instead of always registering two of them: the "normal" (but rarely used) version and the "NR" version used unless wxFULL_REPAINT_ON_RESIZE style is specified. With the new RegClass_OnlyNR, only the latter is registered and used. This is not used yet, but will be soon.
