BREAKING: SQL schema change 

- Redo schema to improve handling of lightweight tags
- Try to clean up empty directories when untracking a project

To resolve schema conflict, run `sqlite3 willow.sqlite` and paste the
following:

ALTER TABLE releases RENAME TO releases_bak;
CREATE TABLE releases
(
    id          TEXT      NOT NULL PRIMARY KEY,
    project_url TEXT      NOT NULL,
    release_url TEXT      NOT NULL,
    tag         TEXT      NOT NULL,
    content     TEXT      NOT NULL,
    date        TIMESTAMP NOT NULL,
    created_at  TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP
);

If everything works as expected, you can `DROP TABLE releases_bak`.
