Toshio Kuratomi 44935a5db6 Add a (disabled) code-smell test for detecting _ variables
We are reserving the _ identifier for i18n work.  Code should use the
identifier dummy for dummy variables instead.

This test is currently skipped as someone needs to generate the list of
files which are currently out of compliance before this can be turned
on.

# Only needed until we can enable a pylint test for this. We may have to write
# one or add it to another existing test (like the one to warn on inappropriate
# variable names). Adding to an existing test may be hard as we may have many
# other things that are not compliant with that test.
# Need to fix everything in the whitelist in order to enable a pylint test.
# We've settled on "dummy" as the variable to replace dummy variables with
# (vast majority of these cases)

# before enabling *this* test, we need to create a full list of files which we need to fix
