[FIX] fixed timestamp date to be the actual date if grabbing can't keep up with the time interval (e.g. if you specify high skipframe values, or the webcam is slow to start)
[ADD] added keepalive to capture session if interval is smaller than 2 seconds so we can capture as fast as possible
[ADD] added SIGINT handler (ctrl-c) to teardown the capture session
Merge branch 'feature-timelag-fix' into develop
[ADD] added creation of subdirectories if in outputname
[ADD] if using -x and -y we tell QTCapture about it, so we use less resources (useful if many cams don't allow for more simultanious capturing)
[CHANGE] capping the framerate now at 6fps to allow for multiple high res cameras to be captured simultaniously
Merge branch 'feature-multicam' into develop
[ADD] added resume functionality - is default now, no overwrite unless -z is given for time based snaps
