Organize level models inside a levels/ directory

[joshlory]

Put all the models for the Level single table inheritance into one folder. Based on the answer to this question: http://stackoverflow.com/questions/18934115/rails-4-organize-rails-models-in-sub-path-without-namespacing-models.

My vote would be to keep Level (the base class) in the "base" directory. Otherwise, this looks awesome!

I love it!

I'd have a mild preference for keeping level.rb in the subdirectory, just to keep tab completion simpler. Asher, why do you prefer it in the base directory?

Though tab completion simplicity would be nice, it'd also be nice to see the model files for DB tables in the base directory (e.g., there is a levels table, though not a applab table). By no means am I blocking the PR as-is, though.

Any further comments here? I'm leaning slightly towards leaving Level in models/levels/level.rb.

SGTM. And it'd be trivial to move the file later, if we find a compelling reason to do so.
