Instead of skipping clashing dists, rename them.

I came up with the distribution renaming scheme halfway through the process.
This rehabilitates them.

Also, Macro became Text-MacroScript.
Don't skip releases just because they clashed.

All of these are valid releases, but their distribution name clashes with
another distribution.  I did them before I came up with a good renaming scheme.

Also: authors/id/V/VI/VIDUL/cwd.tar.gz became authors/id/V/VI/VIDUL/swd.tar.gz
