Window customization on Win32

Linked with #2143
I've tried to add the ability to change window "chrome" on Win32 in Glut part.

```cpp
void ofAppGlutWindow::setChromeWindow(bool titleBar = true, bool borderFrame = true)
```

What do you think about this?

* **Without title bar**   

```cpp
int main(int argc, char *argv[]) {
    ofAppGlutWindow window;
    window.setChromeWindow(false);
    ofSetupOpenGL(&window, 1024, 610, OF_WINDOW);
    testApp * app = new testApp;
    ofRunApp(app);    
}
```
