Reverted change to scanner that I accidently commited while fixing a merge conflict. (should be fixed anyway, but not here, to prevent merge conflicts later etc)
ref #10 - changed a value
Refactored board size calculation

The calculation doesn't depend on anything in the getStones() function so i moved that out of there.
[Close #128] Stop camera scanning while doing board detection
[refs #131] Fixed bug where the painted debug image was used when doing board detection.
The problem was, that the global img0 Mat pointed to the same data as the camera_frame Mat in Scanner.cpp, which got modified in line 126 with paintedWarpedImg.copyTo(camera_frame);
Merge branch 'Go_Scanner' of github.com:augmented-go/augmented-go into Go_Scanner
caching the board size for subsequent calls to the scanner_main()
fixes #125 - fixed this bug

ref #10 - added variable clustering. the scanner now caches the last known board size and selects the clustering calculation value after it. if the board size is unknown we try random values until the correct one is found.
