Naked groups of LI in HTML5 mode will now have an inferred UL applied to
them consistent with HTML4 and earlier modes.
Test case added.
Note that three regressions were updated in favor of this corrected behavior.
- 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.
