setField is working around setters but makes it not work with some libraries

[Magnesus]

I am trying to use Actuate with Heaps.io but since it uses setField and not setProperty it failes to do anything (since set_x does update the state of Bitmap so the engine knows to update it's position). Would be great to see an option to switch to setProperty - at the cost of some performance it would make using Actuate with Heaps possible (without falling back to using methods).
