City council meetings

City council meetings now rendering for Philadelphia!

### Local municipality navs
We first spent some time wiring up the local municipality nav menus and handle two tiers of jurisdictions: state and city. Here's what Philly looks like:

It's set up to handle multiple local jurisdictions based on the abbreviation field (in the case for PA, anything starting with 'pa-'). If/when more than one city is present, it will be listed on that same nav bar.

### Rendering meetings

Decided to render meetings as a table, but it looks like we don't have any table styles:

Perhaps @acacheung could take a look?

@walter doesn't look like we have specs for bills, listing people, etc. Do you want specs for rendering meetings?
