**Preview Window Enhancements**
Several bug-fixes for IMAP. Properly disconnecting after checking is now working. Quick check was previously causing the last message to appear in the message list repeatedly in some cases and not update the message count. And an efficiency issue, when deleting several mails at once, expunge is now called only once.
The custom date/time format enhancement from the previous release did not save and read the desired custom format correctly. This has been fixed.
