Handle multiple years and many more jurisdictions

Our current URL scheme is not scalable.

We are currently working on scraping all audited financial accounts data for every public body in Canada.

We need to update our url schemes and how we generate and display data to support this:

canadaspends.com
|-> federal
 |-> <dept>
   |-> <year>
 |-> <year>
|-> ontario
  |-> municipalities
    |-> <city>
 |-> <dept>
   |-> <year>
 |-> <year>

This probably needs more thought
