Add a TODO noting the reason we're getting a test failure (both old and new code are in at the moment)
Break things: remove the old 'get' method from TameObject and update so that the core files now only use the new property manager
Fix render queue behavior type definition. We'll need to alter the way behaviors are handled, I think.
Adapt sprite & watch to use the new property style
Refactor the rest of the engine to use the new property style
Use the new property style in the render test (is now much more readable)
Add some notes about how the property manager works
