Do not keep TABLE in version control.

TABLE was always a debugging tool, and permitted everyone to see the
effect of changes in the string-format configs.  The hash-format
configs being much more readable, distributing TABLE becomes much less
necessary.

Being able to produce a TABLE is kept, however, as it still is a
useful debugging tool for configs, what with multi-level inheritance
and all.
