This time there were many chenges, so fix them:
- killID -> killmail_id
- killTime -> killmail_time
- characterID -> character_id
- allianceID -> alliance_id
- corporationID -> corporation_id
- shipTypeID -> ship_type_id
- finalBlow -> final_blow
- fix kill date/time format
- prevent KeyError's in the future (add exception handler)
