plotann.py fails on Ubuntu 20.04/python3

[hronellenfitsch]

Hello.

I recently installed astrometry-latest (0.80) on Ubuntu 20.04 with setting the python executable to python3 (which is the default on 20.04). Following this, plotann.py failed with an AttributeError:

AttributeError: 'plot_args' object has no attribute '__getattr__'

This seems to be an issue with the plot_args object and SWIG. It turns out that it can be fixed by changing line 62 in plotstuff.py from

return self.pargs.__getattr__(name)

to

return getattr(self.pargs, name)

I hope this report helps others with the same issue.
