Add Incorporeal status

[txm3278]

The dnd5e system solution to a token that can pass through other tokens is to set Ethereal. This modules makes tokens with Ethereal invisible to other tokens with basic sight, so currently a creature like the Will-o'-Wisp is impossible. I originally requested this to the system but was told it doesn't make sense for them to add it since it would work the same without this module.

I think RAW you cannot move through the space of hostile creature that has the Incorporeal Movement feature. But correct me if I'm wrong. If it's RAW, I can eventually implement auto detection of the Incorporeal Movement feature and prevent creatures that have it from blocking movement.

Wraith for example has the incorporeal feature, https://www.dndbeyond.com/monsters/5174960-wraith, it would allow the wraith to move through other creatures but not other creatures to move through the wraith. This is the same for all other mentions of incorporeal that I found, including the Warrior of Shadow monk.

I am unsure about things like spiritual weapon and if they actually occupy their space or not. Trying to find a RAW description of that

In the case of spiritual weapon, it's not a creature so shouldn't block movement but that feels more like a system request
