Typos in install script

[allisterbrizan]

You miss-spelled some of your filenames so /usr/share/freemix isn't created and videosource.py doesn't copy. This is the offending snippet fixed:

      scripts=['src/freemix'],
      py_modules=['controller','engine','gui','sequencer','videosource','videotable'],
      data_files=[
                  ('/usr/share/freemix',['README']),
                  (
                   '/usr/share/freemix/img',['img/freemix.png',
                                        'img/freemix_small.png',
                                        'img/empty.png',
                                        'img/VHSTapeOpen.png']
                  ),
                  (
                   '/usr/share/freemix/docs/',['docs/key_accelerators',
                                          'docs/use']
                  ),
                 ]
      )
