------------------
* Registering projects and uploading releases now requires authentication.
* Every project now has an owner, so only the user registering the project can
add releases.
* md5sum is now properly listed in the release link.
* Project names can now have dots ('.') in them.
* Fixed a bug where filenames was mangled if the distribution file already existed.
* Releases now list both project name and version, instead of just version in the admin interface.
* Added a sample buildout.cfg. Thanks to Rune Halvorsen (runehopera.com).

* Projects now has an associated owner, so old projects must be exported and
imported to a new database.
