MantidPlot Crash with matplotlib

Description

Quote from Tim Charlton 

Also I found that running a plt.show() from matplotlib crashes mantidplot. I had a similar experience running with only an ipython shell.  In this case the shell either dies or restarts.

This is a known issue with the current single-process asynchronous python scripts. There is a workaround that is described here: http://www.mantidproject.org/MantidPlot:External_Python_Plotting_Package

Using the second example on the given link, I get the following error (no crash): 

TypeError: threadsafe_call() got an unexpected keyword argument 'color'
  at line 5 in '/home/2zr/mscripts/test_matplotlib.py'

and no plot appears.

I'm making the executive decision that in spite of the above error, this doesn't cause Mantid to crash. However, keywords cause the command to fail and not produce a plot which is a problem. So, I'm creating another ticket to address this.

OK, I've created #9092 to address this.
