Refactor/deanonymize-get-prop-funcs

[mrufsvold]

I don't want to break the api, so I created a simple get_property function that looks up the correct function and then returns an anonymous function with "this" inserted in the first position.

I commented out a warning log about deprecation because basically every function call in the code base hits that warning at the moment. But once everything is moved to using direct function calls, we can turn on the warning to track down the last of them.

To be clear: I didn't change any logic here. Just renamed functions to snake_case and moved them out of get_property

Pushed a doc string and kicked all the tests off again accidentally. Either way, ready for review!

This is awesome, thank you! Give me an hour or two and I can fully review it and run some manual tests that aren't covered (yet) by automation
