Changed how these files are named so it's easier to read in the addon

I am working in another branch on for the index refactor and as I was breaking things out more coherently there I realized that I would rather we use the convention  type-thing.js to name files

That way if we have multiple route object files we could do:
routes-filters.js
views-filters.js
and it'll be easier to find which type of files we are looking for.
