Added test of video with audio. Added GUI to select pictures and movies using radiobuttons. These pictures and movies are loaded based on the contents of the show.xml, which fills showDefinition. The showDefinition class is responsible for updating the current texture, based on both the GUI and the current time (will request new frames from a video, if it is playing) Also, now we use the width and height settings of the window from projectorConfiguration when the window is created. We can consider this the first beta (feature complete) version.
