Multiplatform support with CMake and QGLViewer

If Qt4 and libQGLViewer are already installed in your computer, you should be able to compile this by simply running the following commands:

    $ mkdir build_make && cd build_make
    $ cmake ..
    $ make

The binaries are located in the folder ```build_make/bin```.

The App files (RodSoundApp and SimulatorApp) were converted to Viewer files (RodSoundViewer and SimulatorViewer). All the functionalities should be there, except the 'fancy' rendering.
