remove default wxDC ctor to make it impossible to construct DCs without the associated wxDCImpl (this breaks compilation of classes such as wxMirrorDC instead of crashing at run-time); fixed wxMirrorDC compilation after breaking it; renamed wxDCFactory::GetFactory() to just Get(), no need to be repetitive
