Idea: Instead of scanning for deprecation messages, pre-specifiy regexes for all known deprecations

I noticed when I did my initial run-through that there were many duplications of the sort "you tried to access property 'x' but you should have used 'model.x'"

So I went through and collapsed them into regexes, problem solved. It occurred to me there are a finite number of possible deprecations, so maybe it would be easier to just put all those regexes in a file and copy that into config instead. No console copy-paste, covers everything by default, less likely to have new things crop up later.
