Feature Request: Add support for properties

[BigBoot]

Would be useful for example for AnimationTree, something like this:

[OnReadyGet("AnimationTree", Property = "parameters/playback")]
private AnimationNodeStateMachinePlayback _playback;

Please tell me what you think, if you wan't I can also have a go at implementing this and submitting a PR.

Nice idea, I like it a lot! I definitely have _playback = (AnimationNodeStateMachinePlayback)_animator.Get("parameters/playback"); in a few ready methods, myself. 😄

A couple implementation details that jump to mind:

• If there are a bunch of OnReadyGets pointing at various properties of the same target, the generated method should only call GetNode once.
  • This value should also be shared with an OnReadyGet that has no Property, if one exists.
  • But, this is a pretty minor optimization that I would be fine not having, if that makes it easier to implement. (It doesn't affect the _playback example at all.)
• Playing nicely with OrNull would be nice.

I would definitely be interested in taking a PR. 🙂 If that doesn't work out, I'll take a look at it next time I run into a place this would be useful for me.
