@kirill-kornyakov Kirill, good job!

I suggest to use --depth parameter in this command git clone https://github.com/Itseez/opencv.git. Something like:

git clone --depth=1 https://github.com/Itseez/opencv.git

This will allow to reduce "clone" data transfer from ~380Mb to ~100Mb.

P.S. This change loses correct "Version control" information from cmake configuration output (because there are no tags info available with selected little depth):

General configuration for OpenCV 3.0.0-dev =====================================
  Version control:               82c67ab

vs

General configuration for OpenCV 3.0.0-dev =====================================
  Version control:               2.4.9-3654-g82c67ab

Well, Alexander, if you have some spare time to finish this pull-request, that would be great! :) As you can see, I've created it a month ago, but I still don't have time to finish it. I think it should OK to use Travis while we're not ready to add contrib to the main BuildBot farm.

If you don't have time, I understand, but that means that we should wait for me. Who is terribly slow...

Do i have something to do to validate ?
