- Rename snapshot directory from ".snap0" to ".snap".

- `quilt diff: Speed up file list generation in `quilt diff'.
  Don't use modified_files anymore. Instead, add first_modified_by
  function. I want to get rid of the patches_per_file cache;
  it sometimes was not brought up to date. Some cleanups.
- Add test/snapshot.test.
- Fix two errors in the date format in quilt.changes.
