Improve support for development against a local server

[aaronbrethorst]

Preconditions

I am using the onebusaway-docker repository to run an OBA server on my development machine, using the following commands to run a server for the Champaign-Urbana area of Illinois:

GTFS_URL=http://developer.cumtd.com/gtfs/google_transit.zip docker-compose up oba_bundler
docker-compose up oba_app

Expected

I should be able to launch the OBA Android app in the emulator, change the app's settings to make the current OBA server URL http://localhost:8080/onebusaway-api-webapp, and actively use the app, just like iOS can.

Actual

1. I run into security issues with trying to access http://localhost:8080 — this is fixed with PR Allow use of a non-HTTPS localhost OBA server #1123
2. Even after applying PR Allow use of a non-HTTPS localhost OBA server #1123, I am still running into issues loading stops in the specified service area. Let's track this down and get the android app to work as well as the iOS app.
