[Calendars/Code Cleanup] Fixed a calendar issue with multiple day busy events not occluding active events if the busy event started or ended outside of the current month.
* [CHD-3370] [Custom Fieldsets/Code Cleanup] Deleting custom fieldsets is not possible.
* [CHD-3369] [Custom Fieldsets/Code Cleanup] Fixed an issue where custom fieldsets didn't link when applied to newly created tasks.  The fields were set properly, but the fieldset itself didn't show up on peek or profile.
* [Platform/Automation] Updated the SQL automation scripts for 6.4 in the install/extras/automation/ directory.  These allow the creation of a default database without having to run the installer.
* [Mail/Attachments] When displaying an HTML attachment in the browser, the UTF-8 character set will now be used.  Many browsers were defaulting to Latin-1, which was showing corrupt characters for multibyte languages (like Chinese).
* [Workspaces/Wizard] Fixed an issue in the 'Help me create a page' wizard that was creating unusable workspaces.
[Code Cleanup]
* [CHD-3374] [Calendars/Usability] Reimplemented the floating calendar helper for picking dates in all date-based input fields (e.g. task due, ticket waiting until, custom fields).
* [Worklists/Aesthetics] The CSS styles for worklist hovering and selecting are now marked !important so they always override any other colorization.  This is helpful when making VA behaviors that add new styles to worklists based on priority, etc.

[Code Cleanup/Calendars] Date input fields will now automatically calculate a relative width based on their parent.  This compensates properly for the two icons on those fields where a simple width like '98%' doesn't.
* [CHD-3380] [Knowledgebase] Fixed an issue with knowledgebase navigation in workspace tabs.
* [CHD-3381] [Mail/Reply/Custom Fields] Custom fields and fieldsets can now be set again while replying to tickets.  Previously, this functionality set values for all custom fields regardless of whether or not they changed.  This caused problems because workers that were changing the custom fields on a ticket during the course of a long reply would have their changes overwritten when the reply was sent.  Now the worker sending a reply may choose which custom fields to set, and the values for everything else will remain unchanged.
[Code Cleanup/Dates] The smart date inputs will no longer auto-focus the first autocompleted result.
* [CHD-3383] [Mail/Reply/Usability] When replying to a ticket, the "Would you like to move this conversation?" question now shows the current group and bucket in the default answer.  For example: "No,  leave it in the inbox of Support".  Previously, workers had to open the picklist and scroll around to find where the conversation was currently located before they could decide if they wanted to move it -- this wasted the time spent moving a conversation only to find out that it's already at the destination.

* [Dates/Usability] Fixed a few rounding errors in relative dates displayed throughout the UI. For example, a relative time of '59 minutes 31 seconds' was being rounded up to '60 minutes', when it should display either '59 minutes' or '1 hour'.
[Code Cleanup] Reply 'move to'
[Code Cleanup/Support Center] Always capitalize column names in filters on SC worklists.
[Support Center] Added the ability to render the group and bucket of on ticket history worklists in the SC.
