title: Remove bokeh logo from a list of figures
body: <p>You can easily remove Bokeh logo from a single figure doing the following:</p>
  
  <pre><code>from bokeh.plotting import figure, show
  from bokeh.models.tools import PanTool, SaveTool
  
  p = figure()
  p.line([1, 2, 3, 4],[1, 4, 3, 0])
  p.toolbar.logo = None
  p.tools = [SaveTool(), PanTool()]
  show(p)
  </code></pre>
  
  <p>or just using <code>p.toolbar_location = None</code></p>
  
  <p>I, however, didn't manage to hide it when having multiple figures:</p>
  
  <pre><code>from bokeh.plotting import figure, show
  from bokeh.models.tools import PanTool, SaveTool
  from bokeh.layouts import gridplot
  from bokeh.models import ColumnDataSource, BoxZoomTool, WheelZoomTool, LassoSelectTool, BoxSelectTool, ResetTool, \
      PanTool, TapTool, SaveTool
  
  tools = [PanTool(), BoxZoomTool(match_aspect=True), WheelZoomTool(), BoxSelectTool(),
           ResetTool(), TapTool(), SaveTool()]
  
  figures = [figure(plot_width=800, plot_height=800,
                    tools=tools, output_backend="webgl", match_aspect=True) for i in range(2)]
  
  figures[0].line([1, 2, 3, 4], [1, 4, 3, 0])
  figures[0].toolbar.logo = None
  
  figures[1].line([1, 2, 3, 4], [1, 4, 3, 0])
  figures[1].toolbar.logo = None
  
  show(gridplot([figures], merge_tools=True, sizing_mode='scale_height'))
  </code></pre>
  
  <p>I've also tried <code>figures.toolbar.logo = None</code> but of course it doesn't work as it's a list and it has no such attribute. How can i do that?</p>
