#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.
This can be simplified down to two lines, and I would rename the method:
```ruby
def street_address_for(address)
  return address.street_1 if address.street_2.blank?
  "#{address.street_1}, #{address.street_2}"
end
```
