fix bug #40380. get date searches and date filters to work.

preflight the date picker with today's date.

there is no date picker yet, but there is a simple xul textbox.
d/m/yyyy is the supported format.  there are plans to implement
a date picker in XBL which prevent user error.  right now, a user
could type "foobar" for the date.
