* lord save me
* UI/ChatBox: Use the new `defStyle` param for `RenderMarkup`
The previous iteration didn't work because `AddMessage` can't inherit
its color from the PushColor (since we're not doing actual tag stacks
anymore).
* rebase touchup
* Converted all SnapGridPositionChangedEvent subscriptions to AnchorStateChangedEvent.
* Fixes power tests with new anchored requirements.
* Moved AnchorableComponent into construction.
AnchorableComponent now uses Transform.Anchored.
* Fixed bug with nodes, power works again.
* Adds lifetime stages to Component.
* Update Engine to v0.4.70.
