Update implementation for dedicated release table

This patch updates the implementation for the dedicated release table.

First of all, it updates the model types and adds the new
`crate::db::models::Release` type for representing releases in the
database (which are just pointers to the released artifact).

The `db artifacts` command is updated by using a LEFT JOIN with the
"releases" table.

The `release` command is updated as well, though the change was a bit
more complex.
First of all, a LEFT OUTER JOIN was added which is essentially the same
as the filter for un-released artifacts from before the change.
Then, a `.select()` call was added, so we don't load all the objects we
don't need anyways.
This reduces overhead not only with the database querying but also in
the code here, as we do not allocate objects from the database we
destruct right away.
The updating of the artifact object in the database was changed to
generate a new release object in the "releases" table, of course.
