Added OpenCV project properties in VS project

Added project properties that link the Visual Studio project to OpenCV.
Added properties for both `Debug` and `Release` configuration.
Only links to the library `opencv_core` as of now. Other libraries can
be linked by following the instructions in the tutorial.
Tutorial:
http://docs.opencv.org/doc/tutorials/introduction/windows_visual_studio_Opencv/windows_visual_studio_Opencv.html#the-local-method
Link to `opencv_highgui`

Added `opencv_highgui` library to project properties.
Deleted *.sdf from Git (VS intermediate file)

*.sdf contains some intellisense information. It is build from source
files by Visual Studio and thus can be deleted.
Git won't consider adding it again as *.sdf is ignored since

Link to opencv_imgproc

Necessary for video input tutorial.

slnkcctr.cpp: Portabilized `main` declaration

Now uses `main` declaration as in C++ standard and OpenCV tutorials,
e.g.

http://docs.opencv.org/doc/tutorials/highgui/video-input-psnr-ssim/video-input-psnr-ssim.html
slnkcctr.cpp: Reformatted
Displays video stream from camera

Tutorial used:
http://docs.opencv.org/doc/tutorials/highgui/video-input-psnr-ssim/video-input-psnr-ssim.html
Added `double` output formatting for better readability
slnkcctr.cpp: Added `printProperties` for debugging cameras
main: Prints camera properties
main: Made frame width and height configurable
Set them to e.g. 1024 and 768 resp. in the "Configuration" section in the beginning of `main`.
Niceified info message
slnkcctr.cpp: Added `endl` into respective include comment
slnkcctr.cpp: Added namespace include comments
slnkcctr.cpp: Removed one properties print (not needed anymore)
slnkcctr.cpp: Generalized properties printing using set of properties
Moved implementation of properties printing in a separate class
slnkcctr.cpp: Removed unused includes
