Convert URLs from Query Strings to Paths

[mattkendall]

The current URL configuration uses query strings to send lat/lng requests to the server. It'd be much more modern to send it as REST-style URLs. This requires changing:

• urls.py -- needs to be updated to take lat/lng. See the Django documentation for the syntax.
• views.py -- needs to be updated to take the lat/lng as arguments to the view methods.
• services.js -- needs to be updated to send the lat/lng correctly.

It looks like someone is thinking about cacheability. I like your train of thought here.

Even if you issue a Cache-Control header with an Expires on a querystrung url, proxies are notorious for going rogue and making up their own caching rules based on request signatures.

Caching is less of a concern for many of the dev map queries, since they're usually lat/lng queries based on a user's click point. I probably should turn caching on for them regardless, but my primary reason for wanting to switch over is that Django supports flat URLs much better. It'll allow us to delete several lines of code and make the URLs look a little more modern in the process.
