Apply triggers through portals, as sector attributes

[Lwmte]

Currently it's not possible to apply triggers through portals, because trigger is an over-complicated data structure which isn't simply applied as sector attribute, but as abstract position-based entity. We need to make it work just like sector attributes, so it could be applied through floor portals to lowest room below, This would greatly simplify placing triggers on stacked multi-room setups.

It's actually is sector based object, not position based. Main reason historically is that users want to edit an entire trigger at once, not sector by sector.

To preserve that behaviour, some kind of flood selection could be possible? I am not sure how that would work exactly.
