* [CHD-3971] [Web-API/Tickets] The ticket 'owner_id' field can now be set through the Web-API.
* [Web-API/Tickets] The ticket 'org_id' field can now be set through the Web-API.
* [Setup/POP3/Timeout] Fixed an issue that prevented the 'timeout' option on POP3/IMAP mailboxes from working properly.
* [CHD-3775] [Scheduler/Mail] Each POP3/IMAP mailbox can now specify a maximum message size. This defaults to 25MB.  Any messages that exceed this size will not be fully downloaded, and instead a placeholder ticket will be created with the From/To/Subject headers and a warning message. This fixes an significant issue where very large messages can block a mailbox from downloading any new mail (most providers limit attachments to 10-25MB).  These rewritten messages also include an 'X-Cerb-Parser-Error: message-size-limit-exceeded' header, and a 'X-Cerb-Parser-ErrorMsg' header with a human readable error; which can be used to generate bounces and reject delivery from a Virtual Attendant mail filter.
* [Setup/Mail] The POP3/IMAP mailbox tester will now utilize the timeout setting when connecting to the mailbox.
[Code Cleanup] Updated feature manifest versions to 6.8.5
* [Setup/Mail/Security] Previously, POP3-SSL and IMAP-SSL mailboxes ignored SSL certificate validation in order to work with self-signed certificates on local mail servers. Now SSL certificate validation is a toggle (Enforce/Ignore), which defaults to Enforce.  If you have a self-signed certificate, edit your mailbox in Setup->Mail to disable SSL validation.
* [CHD-3903] [Mail/Reply/Compose] Fixed an issue that trimmed leading whitespace from messages sent by compose and reply.  This made it difficult to paste indented code fragments, XML fragments, Virtual Attendant export JSON, etc.
* [CHD-3969] [Notifications/Explore] Fixed an issue with explore mode on notification worklists.  It was possible for explore mode to start at an invalid position based on duplicate notifications being combined.
