Split JRuleWhen into multiple triggers

[querdenker2k]

I would suggest to split JRuleWhen into multiple triggers, like JRuleWhenTime, JRuleWhenItem and JRuleWhenChannel to not have such a lot unused annotation functions.
What do you think @seaside1 @seime

👍 . Would be a breaking change though and thus need a bit of doc updates.

Yes, but maybe we can start with adding these new JRuleWhenXXXX and keep the old one as well. That way we don't break existing rules for people. It also gives more time to test before removing JRuleWhen (if we decide to do so).

[querdenker2k]

I removed the old JRuleWhen because multiple options will let the code be more confusing.
