PlotWindow: Added NavigationToolbar. Still the same canvas

b_asic/GUI/plot_window.py → b_asic/gui_utils/plot_window.py

+"""PlotWindow is a window in which simulation results are plotted."""

 # TODO's:
 # * Solve the legend update. That isn't working at all.
 # * Zoom etc. Might need to change FigureCanvas. Or just something very little.
