Add matter view

***Some refactoring followed by a couple commits that make it possible to view a single matter.***

To test, view something like http://localhost:3000/matters/7205.

You can also inspect `g_data.event_items[0].matter_id` in the browser console on the index page after entering an address and finding a list of event items to get a matter_id that should work in place of 7205 if you don't have that one.

This also creates a config.js file which may come in handy for people redeploying later (it centralizes some config vars). 

Also this fixes the name (Zone -> MuniciPal) in the title tag for the application.

Finally it makes better use of partials and jbuilder.
