Successfully tested multiple cameras on firewire connected on ManjaroLinux x64 with kernel 3.13.2. A test with OpenCV in multithread is shown. For testing purposes, the standard libdc1394 demo is there (hello_cv2.cpp), without the usage of camwire. Fixed a problem regarding the reference of member 'frame' of Camwire_user_data, which was breaking the internal functions of libdc1394.
