ColorMNet support isn't working at the moment

TypeError: vs_colormnet..colormnet_clip_color_merge() got an unexpected keyword argument 'propagate'

and there is no Hybrid version which supports it atm.

The current version is working in a limited number of cases. I already fixed some bug, but I'm working to a way to fully enable the long memory feature of ColorMNet that represent the most important new feature. I hope to be able to release a new version in the next 2 days.
