Wrapping up the pylint work

[Edward K. Ream]

Completing (really and truly) a project often is the most effective use of time.

Rev f9ae545 contains the latest (and last, for now) version of leo/test/pylint-leo-rc-ref.txt, a copy of the file I actually use to run Leo. #1170 contains all pylint-related notes.

For the first time in at least 10 years:

- I know exactly why each disabled test should be disabled.  Reasons in the rc file.

- No nagging pylint-related thoughts remain.

I now think of pylint as a way of experimenting with Leo's code.  For example, I was surprised pylint passes all files in Leo with a maximum line length set to 90 characters.  As stated in the rc file, anything less than that would, imo, be pure make work, but it's good to know that 90 characters suffice.

Summary

I can now move on to more important matters. #1170 contains all pylint-related notes.
