A version *so* awesome that needs 2 version bumps AND a codename.

Major features:

	- New internal garbage collection (harder)
	- Pack backend rewritten from scratch (better)
	- Revision walker rewritten from scratch (faster)
	- New object interdependency system (stronger)
	- Unique OID shortener
	- Reference listing

In honor of one heck of a music album, released ten years ago,
yesterday.
