Raise new MandrillRecipientsRefused exception when Mandrill returns 'reject' or 'invalid' status for *all* recipients of a message. (Similar to Django's SMTP email backend raising SMTPRecipientsRefused.) Add setting MANDRILL_IGNORE_RECIPIENT_STATUS to override the new exception. Trap JSON parsing errors in Mandrill API response, and raise MandrillAPIError for them. (Helps with #93.) Closes #80. Closes #81.
