User toggling of a mode overrides automatic triggering

This reimplements "snoozing" (manually deactivating an active mode) and the opposite operation (manually activating an inactive mode) with the same semantics (the rule owner can only change a manually-applied state after cycling to and then away from that state). It also removes the attempt in ConditionProviders, which was incorrect (and didn't have enough information to make the decision there).

Also fix getAutomaticZenRuleState() which didn't consider snoozing and reported a rule as active in that case (oops).
