Initial setup for assigning the newsletter date
Use default jQuery UI smoothness stylings for datepicker
Allow for the assignment of a newsletter date

This should allow for the preparation of newsletters for different days from when they are published.
Remove the use of an unnecessary parameter
Use the newsletter date to query announcements for a day
Allow for post IDs in a newsletter to exist across multiple dates

This could be useful in the future. Right now it happens to be a fix against a small bug where the current date was always being queried in one area.
