[Code Cleanup] Removed the deprecated insertAtCursor function in Devblocks in favor of our jQuery plugin.
* [CHD-3221] [Login] When logging in from a disabled worker account, a friendly error message is now properly displayed.
* [CHD-3225] [Broadcast] Broadcast will no longer send messages to known defunct addresses, regardless of the worklist filters.
[Code Cleanup]
* [CHD-3226] [Plugin Library/Devblocks] Updating a plugin from the Plugin Library will now clear the global template cache.  This ensures that any UI changes are immediately available.

* [CHD-3228] [Login] FIXED: The "remember me" option on the login form isn't setting the cookie in some browsers.
6.2.1-dev checkpoint
* [CHD-3231] [UI/Usability] Fixed an issue with the 'elastic' jQuery plugin where leaving a textarea that had resized from new content could shift the rest of the content on the page by a small amount.  This often required an extraneous click on form elements like buttons (i.e. one to focus, one to activate).  This was observed in the mail reply form, and in several Virtual Attendant actions that allow placeholder entry.
* [CHD-3234] [Logins/Activity Log] Fixed an issue with the Activity Log entries for login/logout events when MySQL's strict mode was enabled.
