#644 - updates missing/changed fields

Gets #644 started - updates missing/changed fields from the API:

- changes `street` to a concatenated `street_1` and `street_2`
separated by a space.
- changes `zip` to `postal_code`.
- removes `faxes`
- adds icon helper for phone type with specific icons for tty and fax.
- removes `phone`, `fax`, and `extension` from contacts and adds
`department`
- adds `alternate_name` in parentheses next to location name.
I would use guard clauses here and rename the method:
```ruby
def phone_icon_for(type)
  return 'fa-phone-square' if type == 'voice' || type == 'hotline'
  return 'fa-print' if type == 'fax'
  return 'fa-tty' if type == 'tty'
end
```
