- Updated links with working https versions from http.
- Removed rotten links.
- Updated links that have since resolved to new addresses.
- Generated all new po's and pot from existing headers.
- Updated the regression tests to account for the new https:// URLS, and the
changed reference to specification.
Eliminate the redundant test case version file from the recently re-merged
regression testing suite. Regression tests are now automatically versioned
the same as the current tidy source version.
