Full image does not work in locate()

As reported in https://groups.google.com/forum/#!topic/bob-devel/NnnLs17ApOU, it is not possible to use the full image resolution in flandmark.locate().

Started branch 7-full-image-does-not-work-in-locate

Actually, it seems not (only) to be the line which was pointed out in the forum, but it is here: https://gitlab.idiap.ch/bob/bob.ip.flandmark/blob/master/bob/ip/flandmark/cpp/flandmark_detector.cpp#L937

The given bounding box is automatically increased, so that it contains more background. Apparently, it is assumed that the bounding box was located by OpenCV... We need to make sure, though, that this does not exceed the image boundary...
