Scale Trigger and possibly Gradient Trigger support

[guighub]

Is your feature request related to a problem? Please describe. I'm trying to figure out how to automate some 3D effects in my level using gradients and it requires Scale triggers set to "Only Move" to create perspective along with Gradient triggers set to "Vertex Mode" to fill the vertices.

Describe the solution you'd like Addition of a ScaleTrigger() object or similar and maybe a GradientTrigger() object would really help!

Describe alternatives you've considered I was maybe going to try Move triggers instead of Scale triggers, but it would be a lot more complex than just using a Scale trigger for this situation.

Additional context I'd also like to ask if there's a way to use a trigger that hasn't been added to the API yet by manually inputting the object ID and properties, since so many new triggers and objects have been added to the game since 2.2.
