Backlog: UX: Reduce amount of white things

The size of the input form is making it
difficult to focus on one thing. Help
the brain compartmentalize by making only
the input element that has focus be white,
everything else gray.
Fix: Hide comments on deadlines, keep colors

The gray in the last commit was too pervasive,
and included the background color of deadlines.

Hide comments for deadlines and the next-meeting
story. We might want to add these in some day,
but really if there is a question about a deadline
it should probably be addressed as an agenda item
or in some other way. Or, the time is just not right.
