add 'last updated on' to footer

[derekeder]

Since we are going to be recieving data from the NM SoS on a somewhat inconsistent basis, at least at launch time, we should make a clear note of this on every page.

Let's add a note to the footer that says:

Last updated on Sept 4, 2016

And have the date be the most recent date in the database (whatever the most relevant query is to get that).

pretty sure it was last updated Sept. 15?

[derekeder]

Right - whatever the correct date is!

Also, we should note where it came from. Perhaps something like:

Data comes from the New Mexico Secretary of State. Last updated on Sept 15, 2016.

Is this the date that:

• The updater script last ran?
• The date that we last got data from the secretary of state?
• The latest date that the data that we got from the secretary of state was updated?

I guess the reason I ask is that the first and the third we can probably determine automatically (but with different queries). The second we'll probably want to update manually.
