Fix util includes

Patch a bunch of holes in the adoption of the `module.config(utils)` model. The server should now function properly again. Note that most of these changes should be revised away in the near future (no more xml2js, http goes somewhere else, stopsCache dynamic, etc). See the comments on each line.
