Epidev: pyplot, option non jointive, propagation changed

Temporal plot with plotly instead of matplotlib (interactive) Option of non jointive segmentation (non epithelia): can load it, non optimized yet Option to directly launch epyseg when loading the movie (in the starting part) Output table can be with labels as columns Propagation of label (child and parent): fixed several bugs, and made it faster by looking only at current frame for shape change and label propagation Inspecting: addition of inspect track sudden movement
