Verify that the MoinMoin source files conform (mostly) to PEP8 coding style.

Additionally, we check that the files have no crlf (Windows style) line endings.

# After doing a fresh clone, this procedure is recommended:
# 1. Run the tests once to see if everything is OK (as cloning updates the mtime,
#    it will test every file).
# 2. Before starting to make new changes, use "touch" to change all timestamps
#    to a time before <RECENTLY>.
# 3. Regularly run the tests, they will run much faster now.
