- added support for Asix Presto JTAG interface (thanks to Pavel Chromy and Asix for making this addition possible) 

- added support for usbprog (thanks to Benedikt Sauter)
- make OpenOCD listen for WM_QUIT messages on windows (thanks to Pavel Chromy)
- register at_exit handler to do necessary unregistering (thanks to Pavel Chromy)
- added dummy ETM capture driver to allow ETM to be registered without a capture driver
