feat(smartplaylist): let a rule set match any rule, not only all of them

The conditions were joined with " AND " and nothing else, so a smart
playlist could only ever narrow: "jazz released after 1960" was
expressible and "jazz or blues" was not, which is most of what anyone
reaches for a second rule to say.

`RuleSet.Match` is "all" or "any", and an empty match is "all" — which
is what every playlist saved before the field existed carries, so an
upgrade cannot silently widen one. ParseRuleSet rejects anything else
rather than falling through to AND, since a playlist quietly returning
the wrong tracks is worse than one that refuses to be saved.

Under OR each condition is parenthesised and under AND it is not: AND
is the tighter operator, so an OR-join has to protect a condition
carrying a top-level AND of its own — `days_since_played less_than` is
two predicates belonging to one rule.

The editor shows the choice as a sentence with the control in the
middle, and hides it while there is one rule: with nothing to combine,
all and any are the same query.

Closes #35
