Resolves Issue #4

Resolves Issue #4 (Improved 'not in office' handling for politicians) by
changing the language to 'Not in office'.

Additional future improvements may be warranted, including mentioning
where they went after leaving office.
Resolves Issue #14

This commit resolves #14 - I'm surprised that this is all it took.  I
might add more robust or specific error logging in the future if this
doesn't meet my needs.
Added import files to facilitate cloning

To get a local copy of Shut That Down up and running, you'll need to
import the import_quotes_with_whosaid.txt so the who_said column of the
quotes table is populated (the previous import did not contain that
field).

The import to populate the quote_issues table is also included, which
will be necessary for using /browse_quotes properly.
