Windows build required atlbase.h

While testing the previous commit on Windows I found that I could not
compile windows due to include of atlbase.h. This file is no longer
available in SDKs. It is only available in for money versions of VIsual
Studio. Luckily this include was not needed. So I just removed it and
Windows now builds again with just VS Express. Tested all changes on
OSX, Linux and Windows (including speech on windows, which still works).
