[Code Cleanup/Dashboards/Worklists] Fixed an issue with worklist widgets on dashboards.  Some rows couldn't be deselected, and the actions didn't work.  This had to do with the simplification of the worklist tables into a widget friendly format.
[CHD-3366] [Mail/Reply/Dates] Hitting ENTER in the mail reply 'Next Steps' fields will no longer send the message prematurely.
[Code Cleanup/Worklists] Tweaked smart headers on worklists a bit more to use space more efficiently with lots of columns in a very narrow container.  Additionally, if cells absolutely can't fit their contents (a huge email address with no character breaks) then they'll be cropped.
