Sagan Git Update

[Champ Clark III]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Crash recovery for SQL (MySQL/PostgreSQL/etc) for when Sagan is doing
direct database writes.

When Sagan "crashes", it may not be able to properly write out the
"last_cid" information.

The update checks the event tables MAX(cid) to the sensor tables
last_cid. If there is a mismatch, the last_cid is rolled forward and
the mismatch is corrected.

This is a step to hopefully clear up duplicate INSERT records when an
event is triggered and the last_cid is incorrect.
