[Gridflow-dev] cv prefix replaced

[Mathieu Bouchard]

[cv.Invert] is being renamed to [cv/#Invert] and everything else in the 
same way. Please update your patches accordingly. If anyone cares, I'm 
gonna provide aliases, but I'd rather not. (unlike for [demux], which was 
used in simply way too many patches...)
