Fixed up qttracereplay and trace graphicsystem a bit.
- Added "qttrace" to binary file, making it possible to do a sanity verification of the input file in qttracereplay - Sanity check input binary file, both for existance and for content in qttracereplay - Console app on windows and mac - Added helpful output for -h and --help command line options Reviewed-by: Samuel
