* [Virtual Attendants/Simulator] Implemented Virtual Attendant simulator output for the 'Send email to notified worker' action in 'New notification for me' behaviors.
[Code Cleanup/Virtual Attendants] VA group macros owned by groups only show up on that group's profile.  VA ticket macros owned by groups only show up on tickets in that group.
[Virtual Attendants/Code Cleanup] Added more security to Virtual Attendant viewing and editing.
[Virtual Attendant/API] If the Virtual Attendant or 'Custom API request' behavior is disabled then the API will now refuse to run it.
[Code Cleanup/VAs/Calendars] VA-owned calendars
* [Setup/Mail/Parser] Raw email messages can be imported from Setup->Mail by pasting them into a textbox. This simplifies development, training, and evaluations.  Previously, these messages had to be saved in the /storage/mail/new/ directory and then the parser scheduler job had to be manually run.
[Code Cleanup] Updated Mail.php and Parser.php to use the new format for CerberusContexts::getWatchers()
* [CHD-957] [CHD-3037] [CHD-3173] [Setup/Mail/Parser] Incoming mail messages that failed to parse can now be viewed, retried, or deleted from the Setup->Mail->Failed Messages page.  Previously, administrators had to proactively monitor these files on the disk in the /storage/mail/fail/ directory, occasionally move them to /storage/mail/new/, and run the parser scheduled job manually in order to inspect the output.  Failed mail is now displayed in a familiar worklist format with a peek popup to view each message source.
