added shot score tracking and screen ouptut of results

Added a score attribute to each shot to allow the confidence
of each shot boundary to be logged for precision/recall evaluations.
Modified the commandline inputs and film class so that results were
logged to the screen rather than to xml for the sake of fairer
timing benchmarks.
