A cleansing pass, almost entirely cosmetic. Such things as whitespace

normalization, removal of tabs, copyright year updates to changed files,
docstring and comment fixes, and usage of True/False.  I also made a pass
through the NEWS file.

One import was reordered, and after this commit I will move the mmdsr.readme
file to README.mmdsr.

From my perspective, after that we're ready to go.

I will port these changes forward to the trunk.
