Image processing C++ demo

[akorobeinikov]

C++ demo to unify deblurring and super_resolution processing.
In the future, it may include other types of processing (colorization etc.).

[vladimir-dudnik]

super_resolution_demo should be excluded from test cases and image_processing_demo added instaed

[Wovchena]

This is what I have for now

Please add text markers on images (half-images) in case of -orig and -mixed. Something like "O" and P (Original and Processed). Otherwise it's hard to figure out the difference. Also, you may suggest one more mode - diff - show processed image and difference image ( |processed-original| ) side-by side.

Add markers and diff mode.

you need to move demo's README.md file to the root demo folder, rename description subfolder to assets, if you want to keep images separately from sources.
If orig, mixed and diff are mutually exclusive options then it is better to have option like mode which might have these values.
Again, when orig mode is used output screem consist from both original image and only part of resulting image, which cause output screen to have too big width. When mixed mode is used, output screen is not divided equally between original and result images.

please rebase to develop

BTW, just a recommendation. I don't think it is a good idea to rewrite git history all the time:

1. You do it with mistakes like unresolved conflict in be7bd84
2. It's easier to review what changed on github when there are no force pushes.

please resolve merge conflict

@eizamaliev, @fzhar, ping

more comments, but minor ones

[vladimir-dudnik]

let's think on better name for trackbar (unfortunately I do not see how to avoid printing the name, seems opencv does not allow that, it will print slider vals anyway). So, instead of "Processing" which says nothing on the purpose of this trackbar, we may put something like "O | R" to correspond labels or "orignial | result" but this is too long.
