Before we were fetching the entire message body (including attachments) to get the preview text. This patch now offers the ability to fetch a small (128 byte) preview of the email. Also, since this ticket is about speeding up performance, I've introduced NonblockingBatch, which allows for multiple async operations to be executed in parallel easily. I've added its use in a few places to speed up operations, including one that was causing the lag in #3799, which is why this commit closes that ticket.
