	modified:   modules/videoio/src/cap_dshow.cpp
	modified:   modules/videoio/src/cap_pvapi.cpp

Following changes have been made:
1. Some minor bugs have been removed.
2. In the PvAPI module the option CAP_PROP_MONOCROME has been removed because
   this option does not make sense and causes an error if a color camera is used.
3. Instead the new option CAP_PROP_PVAPI_PIXELFORMAT has been added which allows
   to activate the different pixel formats (color modes) of an AVT camera.
4. Since there were two identical defines
   CAP_PROP_MONOCROME = 19
   CAP_PROP_MONOCHROME = 19
   which were also used in the other module DSHOW, the first one with an orthographic
   error has been removed in favor of the second one.
