Designate Current and Previous Council Members

## Browsing "People" shows All CMs
Selecting "People" shows all Council Members in the system _alphabetically,_ even those no longer serving.
See: https://councildataproject.github.io/seattle/#/people

## Solution
Ideally, current CMs would be listed first, with previous members visually designated.
Pacheco, Harrell, O'Brien, Bagshaw, and Johnson could be appended with "(Year-Year)"

Ideally, we could also designate the Council President (currently CM González is serving)

## Easy Fix
Would it be possible to sort by most recent instead of alphabetically?
