Accounts marked as "Other Error" were killed when really they should be
ignored for the moment. I've added further checking on the eve_api
import that ingores down errors (900 and above) and the access checker
to ignore accounts with a status of 3.
This changeset adds a couple of new features to the API, it pulls in all characters on a corp
basis, if a director's API key is available, and updates last login/logoff date/times for each
corp member.
