moving photo url to json

- separating code + data
- also more generic; previously assumed photos were all of councilmembers
use the more concise _.find format
add functions, data to support more people types

(manager and mayor)
UI change: add ‘Show All’ districts option

- And since ‘All’ can’t be “Your District”, we had to make the menu title more generic
making person template more generalized

- also we don’t show it before we populate it so 
  there’s no reason for the dummy text.
- the {{field}} format is just there in case we move this
  to mustache later… we just overwrite those currently anyway.
adds ability to have page for manager and mayor
fixes so jslint doesn’t complain
Disabling the “blue lines” for the moment (text->map)

two reasons:

1) the geocoder is currently not setup to allow CORS
2) feedback from users (Ian, Niel) was that these were confusing. Once the geocoded is update we can try showing points (perhaps with popup info) where we have it.
don’t send district polygon on every request

(since we have it and others in the global `districts` var anyway)
Only update URL for councilmember views

- if we’re looking at ?mayor page, changing the URL to reflect an address is unnecessary and unwanted (since it results in a new page request and that page request gives councilmember results instead of the mayor view).
add temporary info for City Manager
add routes for /mayor and /manager
