Feature request: Use player's assigned actor when they select the party token on the canvas.

[Joshmvii7]

While using a hexploration map where the party all owns the party sheet actor so they can move it, it's difficult to have them roll checks from inline rolls sent to chat and so forth because they don't have their own tokens on the map. Just requesting to be able to count the party sheet actor as their assigned character if possible.

I'll take this, since I will need to be very careful that it doesn't break kingmaker while doing so.
