Still untriaged.

The autoupdate cronjob log indicates FAILURE for a lot of github release log and commit log extractions.

GitHub querying is now more flexible, and constrainted in a few points:

• Version numbers/tags can now be `projname-1.2.3` instead of just `v1.2.3`
• Invalid tags will just be jumped over now.
• EMPTY will remain the default status for the built-in version_exists quick check, but an extra debug messages was added.
• Release notes .task-list extraction is nearly unchanged.
• Changelog entries in tags.atom are now recognized. (Need at least to * asterisk-led bullet points though.)
• Generalized changelog_html cleanup is now applied. Most of the rules are for fixing GitHub fillers.

Note: The autoupdate module isn't publically visible, resides in a private branch.)
