fix projectGenerator project file

* The project generator project file was originally *not* properly
linked against MultiThreadedDebugDLL, which lead to extreamly misleading
crashes when closing derived fstream and istream classes, because
debugging is more interesting that way...

it has something to do with how the compiled libraries are laid out, I
came to believe.

<RuntimeLibrary>MultiThreadedDebugDLL</RuntimeLibrary>

was the big game changer.

* also adds missing GUI elements for ofxGUI in project Generator Project
file.
