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
