Title: Adding support for multi-fingerprint IMAP servers

For a strange reason imap.google.com is distributing randomly two different SSL certificates (all validated by the Google Internet Authority) which makes that Offlineimap refuses the certificate half the time.

For your information, current fingerprints for imap.google.com are:
* `f3043dd689a2e7dddfbef82703a6c65ea9b634c1`
* `6d1b5b5ee0180ab493b71d3b94534b5ab937d042`

In .offlineimaprc, separate each fingerprint by a space in cert_fingerprint like this:
``cert_fingerprint = f3043dd689a2e7dddfbef82703a6c65ea9b634c1 6d1b5b5ee0180ab493b71d3b94534b5ab937d042``
