[Code Cleanup] Updated copyright headers to 2014
[Code Cleanup] Fixed an issue where the jQuery CSS was overriding link styles in fieldsets if they were in tabs.
[Code Cleanup/VAs] Fixed an issue where adding a new Virtual Attendant behavior didn't scroll down to it.  This was caused by new behavior in jQuery UI that focuses the original DOM element when a dialog closes.
* [Mail/Reply/Usability] When replying to a message, the "Would you like to move this conversation?" option now shows the groups and buckets in two linked dropdowns. Changing the group in the first list automatically displays the available buckets in the second list.  Previously, the current group and bucket was displayed as a default "No, leave it in the [name] bucket of [group]" option, and moving the conversation required using a long combined list of all the buckets which was difficult to navigate.  The new way is also more efficient when using keyboard shortcuts.
* [Performance/Worklists/Tickets] When using the "Is in groups of [worker]" filter on ticket worklists, the database query is now optimized if the worker is a member of every group.  Previously, this inefficiently checked the group_id on every result anyway.
* [Support Center/Contact/Usability] The ability to upload multiple files in the Support Center now uses a browser's HTML5 support.
* [Support Center/Contact/Usability] The file type is now set properly on attachments uploaded through the Support Center.  Previously, all uploaded files were being saved as 'application/octet-stream', which forced attachments to download even if they could be displayed in the browser (e.g. images, text files).
