* [CHD-2836] [Feedback/Workspaces] Fixed a bug that prevented feedback worklists from being added to a workspace.
* [CHD-2832] [Web-API/Tickets/Orgs] Implemented the ability to search tickets by organization in the Web-API.
* [CHD-2834] [Support Center/Setup] Added some instructions about how to set the content when configuring the 'home' module.  The previous "There are no configurations options" text wasn't very helpful.
* [CHD-2801] [Virtual Attendants/Mail] Virtual Attendants can now make decisions based on the 'reopen date' field (aka: due, wait until).  For example, one use case is to notify workers when they send a reply with an indefinite 'waiting for reply' status.
* [CHD-2146] [Broadcast/Mail] Added a 'signature' snippet placeholder when replying to mail from broadcast.  This will use the appropriate group or bucket signature for each ticket.
5.7.3-dev Push
* [CHD-2854] [Virtual Attendants/Scheduled Behavior] Fixed a bug with scheduling behavior using 'only latest'. It was removing all previously scheduled instances of the behavior, not just on one object.
* [Devblocks/Platform/jQuery] Upgraded jQuery dependency from 1.5.2 to 1.7.1

* [Devblocks/Platform/jQuery] Upgraded jQuery UI dependency from 1.8.11 to 1.8.17

* [Devblocks/Platform/jQuery] Upgraded jQuery Validate plugin from 1.7 to 1.9
* [Devblocks/Platform/Reports] Updated jqPlot dependency to 1.0.0b2_r1012
* [Devblocks/Platform/Mail] Updated SwiftMailer dependency from 4.0.6 to 4.1.5
* [Devblocks/Platform] Updated the Twig template engine dependency from 1.0.0-beta1 to 1.5.1
* [Devblocks/Platform/Smarty] Updated Smarty template engine dependency from 3.0.6 to 3.1.7
Tagged plugins as 5.8 compatible
* [Calendars] Implemented a reusable calendar tab with events, recurring schedules, active/busy.  A scheduler job creates ongoing future events based on recurring schedules.

* [Calendars/Profiles] Added a calendar tab to each worker profile.
[Platform/Plugins/Search] Fixed some PHP notices when deeply nesting search parameters.
* [Virtual Attendants/Plugins/Platform] Implemented the ability to 'dry run' Virtual Attendant behavior.  This returns information about the decisions that are made, and the actions that would be executed, without actually making changes to data.  This is used in the upcoming simulator for VA behavior.
* [Mail/Parser/Debug] The email parser can now be instructed to save a copy of all incoming messages prior to processing them.  The original message source for each message is saved in the /storage/mail/archive/ directory and organized by subdirectories for year, month, and day.  This mode can be enabled by defining the DEVELOPMENT_ARCHIVE_PARSER_MSGSOURCE constant as 'true' in the framework.config.php file.  This is useful if you want to keep a record of processed messages for audit control, backups, or if you want to recover the original sources for troubleshooting.
* [Virtual Attendants/Scheduled Behavior] Virtual Attendant scheduled behavior that fails to run will now be deleted rather than accumulating in the queue.  The original intention was to retry them, but in practice a failing behavior will continue to fail and it just wastes cycles.
Code cleanup
* [Virtual Attendants/Usability] Improved the way that menus are drawn when editing Virtual Attendant behavior.  This should fix the issue with menus becoming stuck open when opening several popup editors at once.
